This  information is from a gentleman Steve Sewell that really gives great points in helping to identify what E.G.Booz  you have.Steve and i both love research and he was very very good at it, he passed and is missed by all who knew him.
These are some of the most desired and pricey bottles available in the bottle collecting world.
It is also the most reproduced antique bottle on the Market.The Clevenger brothers made the best copy in 1930
of the straight roof version and have fooled quite a few people myself included. I will show also in this
post Clevenger straight and beveled roof versions for the ability to determine an original BOOZ from the Clevengers.

Only one GVII-5 original BOOZ exists and that is in the Corning Museum of glass.
While not extremely rare the GVII-3 is none the less rare and has a high percentage of roof
and corner damage because of the thinness of the glass in those area's of the bottle.It was difficult to blow
the glass into the bottles corners and crevices thus the bottles were weak at those points.This is why the
roof variant on the GVII-4 with the beveled roof was changed. Metal plugs were added in the corner peaks of
the roof in the mold to achieve this.

The bottle was manufactured at the Whitney glass works in Glassboro New Jersey
in the years 1858 through the 1860s and right on up to 1870.
The Whitney glass works had a retail office in Philadelphia at 118 Walnut street
and right next door to them Edmund G. Booz had his store front where he was
selling his cabin shaped Booz bottles to liquor merchants and tavern owners through out the
Delaware Valley.There was speculation that the bottles manufacture date was in the year 1840
but that has since been disproved as Edmund Booz would have been only sixteen years of age at that time,
an age probably a little to young to be a Liquor Merchant.

The original bottle had a paper label wrapper that depicted an early American cabin.
On the rear of the bottle on the roof is the date in bold font 1840
This led many to believe that the bottles date stamped on the roof was from William Henry Harrison's
presidential Campaign Log cabin and hard cider in the year 1840.
Early in the 20th century Edwin Atlee Barbers book titled American glassware and the book by
Stephen Van Rensselaer's American Bottle's and Flasks only fueled the myth regarding the Harrison
presidential campaign.

A publication in 1926 by Hazel Mirkil in the magazine Antiques proved the 120 Walnut had not been in
  existence before the year 1856 as the city of Philadelphia had renumbered their streets in that year.
The reason the city renumbered was simple the Center City portion was growing and  it was easier to label blocks in the city as the 100 block 200 block etc. The old address of Boozs store would have been 26 Walnut street. Booz also had a property directly behind 120 walnut street at 15 Granite street. In the Days the famous Dr.Dyott had his store front at second and Race Front street being located on the river was where all of the business's that shipped goods via the Delaware river. This was only three city blocks from where Booz had his business on Walnut Street. In fact all of the important business locals were on the river for easy access of shipping of goods.

There is sound justification that the mold maker who the Whitney glass works used for the bottle modeled his cabin in the image of a glass workers home which in the early 1840s through up to 1970  dotted the landscape surrounding the old Whitney Glass works location in the heart of Glassboro. The glass workers lived in small modest 4 room 2 story homes shaped exactly like the Booz bottle.When you peeled the label off the bottle it now closely resembled the glass workers homes. The last vestiges of these old homes came down in 2007 as part of the down town revitalization project   the town of Glassboro was instituting.Glassboro has done a terrible job preserving its rich glass industry.
Only a handful of the original colonial homes still stand today.The 5 point intersection where the Stangers had founded the second glass works in New Jersey in 1775 has lost all of its historic charm with the original Stanger mansion  house as the only standing structure from the original works.

The bottle was blown in a hinged mold which opened and closed diagonally.
A treadle mold was used applying foot power to the mold which allowed the master blower to close the mold around
the gather of glass when blowing into it and than opening it when he was finished blowing the bottle.
When the bottle was released from the mold it sat on a steel pedestal 2 7/8s in diameter.With the bottle now resting on the pedestal the slight circular depression seen on all of the Booz base's was left.The pedestal had been designed to move
independently resting on a large pin.When the glass blower was finished blowing the bottle he was able to move the bottle
towards him for easy removal from the mold.With the bottle now removed from the mold the blow over portion of the glass was cracked off.Now it was the gaffers turn to place the the applied top to the bottle. Once that task was completed the
bottle was placed into the annealing oven which had a lower temperature than the main furnace which allowed the bottle to gradually cool.

To identify an original Whitney made GVII-3 straight roof Booz from the Clevenger version are as follows.

On the original bottle on the right hand side the word WHISKEY has two identifying marks which clearly show the difference between it and the Clevenger bottle.There is a period after the word WHISKEY on all the original.Sometimes because of a weak mold impression the period is faint but it is usually there none the less.The second identifying trait is when viewing the word WHISKEY left to right the first three letters WHI are on the same horizontal plane however beginning with the letter S the
the letters SKEY are shifted down slightly on a lower horizontal plane.On the Clevenger version the word WHISKEY lines up
nice left to right on the same horizontal plane.The top fork in the letter K in the word WHISKEY is wider than the bottom fork
on the same letter.The Base the the letter G in E.G. BOOZ'S is closed on the clevenger version the G resembles a letter C

 on the front roof of an original Booz,both the beveled and straight roof versions have the embossing in three lines reading like this
When looking at the letters the following is true on all original BOOZ bottles.The C in the word CABIN should be directly
below the first O in the word BOOZ'S.The letter S in the word WHISKEY should be directly below the C in the word CABIN
You should be able to draw a straight line down through these letters where they line up.

On the Clevenger version the same letter K is larger on the bottom fork of the letter.
The Clevenger version of the bottle.This is a picture of the side of the bottle.Look at the word WHISKEY.
The embossing is applied neatly straight left to right.Look also at the letter K,notice the bottom fork
is wider now on this version.This is another good way to tell an original straight and bevel roof version
from their Clevenger made counterparts.
