So...I could sure use some help from all you experts.

I've seen a local advertisement for a S&W Model 10 revolver that the seller states was issued "by the Air Force to a pilot in 1974". Unfortunately, the seller does not offer any photos with his advertisement. I've sent an email to the seller requesting photos and additional information such as markings identifying it as USAF issue, barrel length, etc.

If I follow up on this ad and either get photos or actually see the firearm, what should I be looking for to ensure that it is actually USAF issue? For the price the seller is asking, I'm sure I could make some resale profit, if not add it to my collection.

Thanks in advance...
