Black paint mystery?!

[Mac Cat]

“eue/40”, eagle over swastika above “WaA300” and then “P.08”

eue = Otto Reichel, Ihn. Rudolf Fisher, Lederwarenfabrik, Lengfeld, Erzbridge,
(Lengfeld is 2 miles south of Suhl, or if it's spelled Lengefeld, that further east by Dressen - both spellings are given)

(The Standard Dictionary of Proof Marks, German Ordinance Codes. p.180 - G. Wirnsberger)

I haven't seen a stamp that clean before and the "/40" format may mean "1940".

The "WaA300" is a German Army "Waffenamt Inspectors Number" stamp.
300 would be correct for Fisher, Rudolf (Reichel)
(Luger Holstgers & Accessories of the 20th Century, p. 203,, - Eugene J. Bender)


And "P.08" would be correct.

It's just the date that didn't look right to me. I haven't seen another done that way.
