Brophy's book on Marlin History has sn information.
I am not sure, but most of what I have read on the net leads me to believe that Marlin made National fire arms designs after National fire arms closed down. I have a National Fire arms 12 ga. pump, and it has absolutely no markings that indicate marlin had anything to do with it.
No. Even if they did, it wouldn't be safe to fire them.

looks like the model 80 was manufactured from 1935-1939. there was two differant variations of it.
It should be marked on the barrel
Absolutely not!
NO! Your Marlin model 30aw(all weather) was chambered in 30-30Win.That is the only cartridge that will fire correctly in your rifle.
The Marlin Model 795 rifle does not utilize clips, but has a 10-round detachable box magazine. The rifle itself has a magazine disconnect, and thus will not fire unless a magazine is inserted.
No a comerical round is not avalible to the public
I believe they do, along with Marlin Fire Arms
