No idea of date, but it's older than the date they started requiring serial numbers. Google may reveal more info. It is NOT Damascus. Damascus barrels are usually brownish and you can physically see the steel is kinda spiraled. Don't think I've ever seen a 410 with Damascus barrel? Or a single shot Damascus for that matter. The proof 7 tells me it's capable of handling standard ammo.
It's a model 94A and if I remember I might look it up in the blue book to find mfg dates.
