I traded for one today (no dash) S/N 198XXX...SCSW puts the gun somewhere between 1957 and 1962...It is a flat latch if that helps anyone narrow the date down...I valued my trade at $700 (we traded even)......Ben
AAV is listed in the Standard Catalog as being from 1985, but only a letter can tell you for sure when it left the factory. The absence of the barrel pin and the three-alpha serial number immediately put it being from after c. 1982-83.
The other stuff in the yoke cut does not help with dating. 75237 is a parts-tracking number, used during assembly. The other mark is probably A7. That would be a fitter's or inspector's mark. It means nothing now.
The Goodyear grips are of course, an aftermarket addition.
