These are cool old guns. I have one in 12 ga that I paid $500 for some years ago. Mechanically its fine but the finish not so much. Like most old pumps they don't have a disconnector so if you hold the trigger back they will fire as fast as you can pump the forearm. Here is what the 2018 Standard Catalog of Firearms says. See the note at the end of the text about the 16 ga.
Hi. Welcome to The Gun Rack. No doubt, your journey here has been a long one. But rejoice! For you have arrived at a place like no other. A place where goats and Chevettes dwell in harmony. A place where Glock fanboys and HiPoint hipsters coexist with mutual respect for one another. A place where even crocs are considered cool. Well, not really, but those that wear them are still accepted. Hell, even the owner of the site is a kilt wearing Californium. So register, log in, and become a part of the most eclectic gun forum on the interwebs. You'll be glad you did 😉
