I started a thread on THR and haven't gotten very much:

I pretty much have given up trying to get the magazine apart, and started reassembling. I noticed I was having a hard time putting the barrel on and couldn't get it to cycle right. Upon further inspection, I found another part that is different from the parts kit I bought. I turns out the piston pin, the pin that holds the piston to the recoil spring, has changed over the years. Mine has a low head. The new one had a higher head that was rubbing against the barrel.
So, do I have an original 1400 or a MkII. Were there that many changes between the two?
