[MrBen]

Hello everyone.  I just bought this nice little gem which was sold as not working and supposedly didnt extend but a little oil and its working well now.

The pencil is about 3in long closed and about 4in extended. 
Roughly 3/8in in diameter making it thinner than most pencils I currently own.

The rear unscrew to expose a lead storage.
It is probably brass inside with gold engraved caps and a Vulcanite/Black Chased Hard Rubber body.

The Rubber body is a pattern  similar  to -o-o-o-
Possibly a simple chain design and although not easily visible there is a Makers Mark or Makers Initials, a cursive capital "L", I can't distinguish the second possible letter if it is another letter at all.

I know multiple makers made these types of pencils primarily Mabie but there is no such branding. 

Is anyone familiar with a pen maker that stamped with a capital cursive "L".

Do anyone have any link to pen maker hallmarks, branding and such?

I've tried Peyton Street Pens and Vintage Pens but it's hard to search for such things.

Any info on the possible maker, the actual name if such a pencil and really anything you care to share is greatly appreciated. 

Thank you.
