after cleaning the gun up a bit, the number questions get stranger.
The trigger guard has # 19933
the barrel, frame and forend all have #19938, the barrels are clearly marked as a grade #4.
the frame is marked as a grade #3, but it looks like it was heavly stamped over a #4.
I tryed to get photos of the numbers but they are not very good.
Now I am more confused than ever, any information I can find out would be great.
