Will a barrel from a Model 1200 Winchester interchange with a Model 1400 Winchester?

You can put the barel from a 1200 onto the the rest of a 1400 mk2. It chambers fires and ejects fine. I built my pump using a piece of steel pipe ground for clearance and drilled one hole to run the pin through. Then I epoxied a wood foregrip to said pipe. This was a couple old grandpa guns left to rust when he got demented. Cut lengths to an inch over the legal thresholds. Now its a decent little " hidden on top of the China hutch" home defender in case a burglar is between me and my bedroom.
