Buckstix, I looked at mine, and I agree with your reading of the barrel stampings. I also have the LR, or whatever, stamp on the receiver flat, with a number 5. I suspect an assembler ID? I also have a 184, and that wierd LR type mark, on the forend hook on the barrel. I also see the 5 on the inside of the Jones lever, facing the triggerguard. I thought I had edited this a second time, maybe can't do that? The # on the barrels is 36??, don't remember right now. That's why I thought this is the serial #, since #1, and #5 would be strange?
