Thank you for your comments. I was out of town and doing family events so no email/Internet.
The 97 is cleaned and reassembled thanks to your comments and this site
http://marauder.homestead.com/files/Model97down.html. The action is smooth and fully functional BUT I cannot get the magazine tube to engage the threads in the receiver! I have verified that the tube threads are roughly 90 degrees off so that they should align when the tube is rotated. It appears that they are the equivalent of one thread too high to engage the receiver threads. Ideas? Is it possible for the magazine tube to assembled to the fore grip 180 degrees out?
Today is a gorgeous day for shooting and I was hoping to take the 97 out.
