Michigan Mike. I took mine apart today to clean it and scrape off the rust. It's a doozy to reassemble.
If the magazine tube is loosened, the stock will become loose and wobble.
I'm sure you know the gun is take-down gun. The knob ahead of the barrel is loosened to allow the barrel to be rotated and slipped off the gun.
I'll have to wait another day before I take it down completely. I've yet to remove the bolt or the trigger group to clean those.
Edited to add:
found it thanks to a member at THR.
