Featured trying to ID designer of clutch using mark & patent info

Thank you in advance for reading my post about this interesting clutch that has a mark and a patent number. Any information would be appreciated. I am trying to find out the designer or manufacturer and have the following information:

(First, I am not sure if the bag crocodile or alligator. )

The mark is very interesting and attached below: It is a cube drawing with the letter "E" in one square and a "P" in another square and on the top of the square there is a square design or symbol I cannot discern Does anyone know what designer or manufacturer this would be or a source I look this up on?

The patent number is 1,623,610, and I have attached the patent. This gets interesting:The patent is assigned to Groove Lock Co. Inc. NYC NY in the 1920s. When I did a google search on the Google patents this company had a number of similar patents associated with the name Harry LEBERMAN in the 1920s (see attached screen shot). Is Harry Lieberman a designer?

I have tried numerous Google searches on various combinations of key words and names and have not found anything.

I appreciate your taking time to read my post.

 

i'd say gator.......i have a wallet like that somewhere....

 

At that date, probably a manufacturer rather than a designer. And suspect neigh near impossible to identify who. (Do you think logo meant to be square nut?)

Interesting. I think it looks to be a square nut. I will research this.

 

Just a thought....I assumed 1920s because of patent but just because patent was 1920s doesn't mean bag couldn't be 1940s or 1960s..just a thought. Is there a database listing vintage bag designers?

 

So disappointing. I googled EP and found the information below on "Electro Plated Nickel Silver." Do you think that that it is what the mark stands for and not a manufacturer?

"What does EP stand for on silver?
Electro Plated Nickel Silver
Many silver plated items bear the marks 'EPNS' that stand for Electro Plated Nickel Silveror 'EP' for Electro Plate."

 

Nope-it’s crocodile. The value is the same between the two animals but only croc has an ISO pore which is that tiny dot in each belly tile (scale). It’s a sensory hair pore-alligators don’t have them.

 

Do caiman? I have a little caiman clutch that came with something else I bought. Made in South America somewhere. Don’t recall where off the top of my head.

edit: it was Argentina.

 

To the best of my knowledge only crocodile has the ISO pore.

 

Thank you for taking the time to reply with this information. It is very impressive that you would know such specific information crocodile skins. This really helps me a lot when I do searches online.

 

Harry Leberman designed the fastening device:
US1774100A - Fastening device for bag handles and the like - Google Patents

 

Thank you. Do you know anything about Harry Leberman such as a bag company he worked for? I tried googling and searching for "Harry Leberman" many many times and the only information that came up was "GROOVE LOCK CO Inc"

 

After looking closely at the mark with the "magnifier tool" in Mac's Preview, I am not sure the second letter is a "P." It looks like the line on the right side continues downward under the rounded top part. Could it be a capital A or a symbol? Does anyone know a vintage bag designer or manufacturer starting with the letter "E"

 

I know nothing about Harry Leberman. I just did one search.

 

I just searched patent 1623610:
Fastening device - GROOVE LOCK CO INC (freepatentsonline.com)

 

Thank you. After much searching for "Grove Lock Co" and "harry Leberman" I can not find them associated with any bag company or any other company except for Grove Lock Co.

 

i’m still waiting for that question to come up on Jeopardy! Just one of those relatively obscure facts i picked up that stuck. Glad i could put it to use!

 

I just put searched for 'patent 1623610'.

 

OH,....I said that last night, sorry
