Good day,  I have acquired many knives and swords from my stepfathers collection to sell and raise money for my mother.  Id really appreciate your expertise.  This scabbard is in question for authenticity?  Ive been told the knife is original.  TIA

LTC Trevor M. Jones, current commander, 1st Battalion, 509th Infantry Regiment, Joint Readiness Training Center. Wearing the JRTC OPFOR O.D. uniform with specific Soviet-style rank, badges and tabs only worn by this OPFOR.  The OPFOR Infantry collar insignia was first introduced by the NTC (Fort Irwin) OPFOR in 1981. And still worn today by Infantry MOS officers & enlisted soldiers today. 

Spotted this on an auction awhile back and had to smile. I didn't win the lot.  Looks like it's made of heavy card stock. 

Thanks for the feedback!

There are a wide variety of civilian A-2 jackets designed to look like military issue, with fake contract numbers, false Air Force designation, etc. And they may have non-military features like pen pockets, made from other than goatskin, etc. Excelled makes a number of different civilian knock-offs, as do many of the other official military suppliers.    

Hi:  I might be late in the game here, but I believe I can help.  Your slide stop is 100% correct.  I’ve looked at dozens of images of unaltered late War (12/44- 7/45) Remington Rand pistols to study this detail amongst others.  The earliest pistol I’ve seen with the slide serrations in the notch is February, 1945 when the darker phosphate parkerizing was still the standard at RR.  Pistols produced during that month exhibit  both smooth and serrated notches.  As of March, 1945, the change to the latter appears to have been complete.     Like anything else, that isn’t to say you won’t find a correct example with a smooth notch during any month of production during ‘45 but it would be an outlier.  I’d be more concerned if a 1/45 pistol had a fully serrated notch as I haven’t observed any, but then again,  it’s possible.  “Never say never, but NUG (normally, usually, generally) is better.” Mike

10 year 7640 is "Record Missing" issued between 1927 and 1936.   15 year 7640 - Records end at 5137 issued in 1959.

PSA-   O'Day's obituary said in his final years he was a docent at the California State Railroad Museum in Sacramento.    For any railroad buffs,  it's well worth a visit if you're ever in Northern CA.

My apologies, I believe it could be a 10 or 15. Ill add a photo.
