Again, thanks to all for the help.

I have been trying to decipher the proof marks on the gun. The is no makers name.
I have never taken photos and posted them so I'll try to describe the marks. I will try to figure how to post photos later.

The receiver has a B with crown over it and a U with crown over it. I believe
this to be German proof used on an import gun?
All my attempts at describing are not 100% accurate. Old eyes and faint marks leave something to be desired.

The side of the rifle barrel has-
0.5 GRN GPm/7?
18 gr Bl.
The bottom of the rifle barrel has a
B G
U
All with crown over them.
It also has
53 ?/M
It also has what could be a makers mark but I can't really describe it. I'll have to try to make a photo.

The shot barrel has on the side-
0.2 gr N. G. P. m/71
18gr Bl.
The bottom of the shot barrel has
BG
U
all with crowns over.
8.8 T/r (maybe on the r)
9.18
811

Again any info and help is appreciated.
thank you all.
