Like they say you learn something new every day. So the shotgun Kassnar was NOT glued but rather still screwed into the stock from below and above ( underneath the release lever) once those two screws were removed the frame came apart. However, not before I had already cut a chiseled the old stock off! Ugh!!!
In any event the replacement stock is only a 70$ mistake replacement and I'm in the process of fitting the new stock to the frame. Also, it turns out that the frame internals are NOTHING like the Stoeger!!! I have a leaf spring and the Stoeger has a coil spring. I'll get it sorted out but it has certainly become more of a process.
I'll get this puppy back up and running shortly. I've already disabled the automatic safety engagement , however, the manual safety engagement is still in working order. Now all I have to do is lighten the leaf spring so that it stays open and low enough so that the shells can be ejected quickly.
I guess I was due for a gun "project" at this point anyway!!
