Barrel Weight Markings and Frame Size

[Eric Estes]

Well that all makes sense now. I had wondered that, seeing a similar difference on the other two I have that seemed to able to be filled in by the fore end weight. Thanks Ed and Edgar.

That leaves the remaining mystery of what the "13" signifies. Unless someone knows I suppose on this older gun before their markings became more uniform it could mean any number of things.

Yes it is true that 9 times out of 10 the barrel weight stamp is almost spot on when included with the forend assembly. But we know this is not the case. Its just a coincidence.

Eric, I no longer have my copy of the TPS, but many on here do. It probably is noted in there. I would guess it's an inspectors mark.
