Long story short, I bought the 336A I found yesterday. It's a shooter, not a collectible, and has some condition issues (I call it character), but I don't think the plug screws have ever been out of the receiver, they look original, anyhow. It has a "T" prefix, but only 3 digits following the "T", so I don't know if it's an assembly # or a serial number. Aside from that, I couldn't find any other numbers on the rifle beyond the usual Model 336 stuff on the barrel. (it doesn't say 336A, just simply 336 then SC .30/30 Winchester). No front sight hood, it's long gone.
If nothing else, it'll be a fun shooter.
