This is very simple.....when did the 41 marking on the IRWIN begin?
1) There is nothing to indicate WHEN the 41 marking was started, so forget the WO drawing even exists....there is NOTHING to indicate WHEN the 41 marking on the IRWIN started.
I'm willing to bet a not inconsiderable sum it was between 1943 and 1948. I'm also sure an examination of the actual ORD/QMC drawing would be helpful.
2) The WO drawing says when it was REQUIRED.....once more, WHEN was your 41 IRWIN stamped with "USAAF"? 1945, or 1946 or 1947? It would need to be determined first WHEN the 41 was available I think, the addition of the USAAF could be postwar.
Ok, You asked for evidence that these screwdrivers were in service before 1950. Last time I checked 1947 was before 1950.
Also, technically the Willys drawing does not reflect when it was required it only gives the date the note was added that it was required.
3) To use your example, a "veteran" who enlisted in 1946 or 1947 in the USAAF is......not a WWII veteran. An IRWIN stamped in 1946 or 1947 is not a "veteran" of WWII, it's a used postwar screwdriver that is perfect for a Korean War jeep toolkit perhaps?
Possibly, but probably no more chance than that ink stamped Irwin you bought off Ebay was likely never in the military at all. I'll live on the edge until you can prove it wrong.

4) If you do not have any photos of IRWINs with the tube rivets on them, I understand.
Oh, I not only have the photos, I have the actual screwdrivers. But in all fairness the photos of the stock # one came from someone else.
I'll most likely post them some day but surely not at your request.
