Ha ha ... As what? Post Samples? OOW doesn't need any ATF letter. They were/are Class 2 MFG. Don't need no stinkin' letter. Good try. I'm amused.

ATF gave Collectors Corner (now OOW) a letter to convert M37 sideplates to 1919's 16 or 17 years ago.
If I look hard enough ... maybe I can find my copy of that letter.
I know because I am the one that welded, re-machined and engraved all of those Group Industries sideplates.
Built about 150 of the sideplates as A4's and 1917 (28 M37's).
