Mossberg Model 400?

[BEARMAN]

Anyone know if there is any parts interchangeability between a MOSSBERG 400 12 gauge pump and a MOSSBERG 500 12 gauge pump. I know some of the early MOSSBERGs had one action bar on the pump, whereas now they all have 2 action bars. After doing a little more digging on the INTERNET , it seems the model 400 Mossberg is a lever action .22 called the Palomino . What was reported to me as a model 400 pump 12 gauge must now be a model 500. But who knows?

I have 2 mossberg 400's.
They are actually 400G's, made in Canada by Lakefield Mossberg.
They have 2 action bars and all the parts I have found are interchangeable with the 500's.
