Hi Steve, Johnny, Lugerdoc and Ron
Thankyou for the help and advice.
It was right on the money.After farting around with it some more and paying attention to your replies here is what I got.
On the right side of the gun (inside) there is an L shaped device that is lifted when the mag is pushed in, and drops when the mag is released. By pushing it with my finger while I had the gun apart I figured it is pushed up by the side button of the mag so it stays down when there are bullets in it or no mag.When I pull back on the toggle it gets pushed down by the bolt and doesn't return because the mag is rubbing the "toggle hold open latch" and is kept down.It needs to spring back up to catch the front od the bolt. I need to relieve the pressure on the side of this latch from the mag.
The take down lever is falling when there is no pressure on it because the spring (appears to be a little pin or something)that is inside the bottom of the keyway groove of the lever hole is worn. It is there and seems to hold the lever up if I push up on the end of the pin with my finger nail.
As far as a small letter under the serial number, there is none. There is however a letter 'S' inside the frame in the well where the take down lever goes through.
Do you guys have objection to sanding or filing the rough spots and then rebluing to make your guns look good? I would like to do this to the side plate and a couple of other spots.
Thanks again
