Hi everybody,

I recently picked up a straight razor from an antique shop and I am curious as to how old the blade might be. It is a 5/8 Full Hollow razor, with the following inscriptions:

TANG, Side 1:
F HERDER ABR SOHN
SOLINGEN *Ace of Spades insignia*

TANG, Side 2:
*Two Keys insignia*

It came with what seems to be the original box, on which the following is imprinted:
F HERDER A Sn
Solingen

While looking around through SRP I did find some information on F. Herder, it however states nothing on the possible age of my #78 blade. ((SRP page on F. Herder, SRP forum post on a 6/8 F Herder, Page about a #78, 5/8 F. Herder. I can't deduct anything about the actual age of the blade from these posts.


The case


Two Key insignia


F HERDER ABR SOHN
SOLINGEN


Front view.

I sincerely hope somebody from here would be able to tell me more about the blade (and perhaps F. Herder Abraham Sohn). Thanks in advance.

PS. The scales broke about a week after I had it, while trying to unpin them to look at the blade. I am going to make new scales from oak and try and restore the blade. It will be my first restoration and I'm quite excited about the whole idea.
