I had noticed the plug on the bottom and sides, so that explains those. The trigger does appear that it may have had the ring cut off. It is a rather crude is some ways....but I can see a difference between the way the front and rear are finished. No number on the TG. All numbers match on the bolt. I appreciate all the info.....! I hope its a "shooter", as soon as it warms up I will see what it can do.
