Hello gungadoug,

I'll bet you also have a "5" on the forend hook base. That's where mine also has a "1".

Do you have a 4 digit number on the bottom of the barrels? That would be similar to my "3716". I don't think that's a serial number since it appears no other place. I'm thinking its the barrel maker's number.

Originally I thought that perhaps the 184 was a serial number, but I find it no where else. Since yours also has this number, it must NOT be a serial number.

I find the no. 1 on all the major parts, like serial numbers are found.

Got any pictures of your gun?
