Unknown 22 Magazine Tube

[*lawrence]

Does anybody have any idea what this mag tube is for?

It's just under 15 inches long.

Any help would be appreciated. Perhaps Winchester??

I have a NORINCO EM321 pump action .22 takedown. It is almost a direct copy of the Trombone.
The rod in mine measures 14.75 inches from end to end and the O/D of the rod is .351"

OK, that's a good clue. Thank you.

Turns out to be for a Remington Model 12
