These guns are pretty scarce. I believe that Beretta made them from 1959 to 1996 but those dates vary in some publications, perhaps no one really knows for sure. Most of the guns were for law enforcement and the military but some were made into sporting guns for the American market but they didn't catch on and it's believed that the sporters were discontinued after 1971.
There are Silver models, Gold models and Ruby models, all are the same gun with different levels of finish and cosmetics. They are mostly field models but trap and skeet models were also made.
I suspect that parts will be hard to find but Numrich Gun Parts does list the silver pigeon pump on their website, there's no telling just how many parts they actually stock but they do list it.
I see an old Tradeex listing with the price at $569 but they're out of stock. I'd think that it would have to be in really nice shape to bring that kind of money and unless it's in pristine condition for a collector then the market will be very small.
