The serial number is AUP 0928

Any help would be great

More information would be better. Open the cylinder and look for a model #. Should be on the frame and look like MOD. 15-3. Also caliber? Barrel length? Pics?

You've got a K frame .357 Magnum. Looks like a 4" barrel with adjustable sights. Someone else can narrow down things like dates. I don't have that info. These are nice guns. I wouldn't recommend a steady diet of light projectile full house .357 loads. Other than that, shoot it! That is what it was designed to do, after all.

Thanks for your help

Probably early 1987, according to a search here of ‘AUP’
