OK, this is starting to get complicated, LOL!
Here's the scoop, one of my brothers, the flea-market/thrift-store commando, gave me 3 SKS stocks he came across last year, 2 wood ones, and a Hogue rubber stock, that I'd hoped to put into use ( that's what I was after a black polymer or cheese grater for).
I also have been holding on to a very nice wooden stock, that I assumed would fit this 1963, long-collar, triangle-26 paratrooper I have, but i just found out, it doesn't !
Also, that Hogue rubber stock doesn't fit an SKS at all, and I'm thinking it may be for something like a Ruger 10/22, so I can't use that.
What all that ^ means is that I have no need for any gas tube handguards, at all !
(with the possible exception of a cheese grater, and/or spare firing pin, but I'm wondering if shipping one of these will make this trade not worth the trouble).
But, I do have 2 solid SKS stocks to wheel-n-deal with, one very nice, and one in typical used-surplus condition (the other one I mentioned in the OP has no hardware, and is missing a large chip of wood from the lower butt, so it's unusable junk, I believe).
The nicer stock has a side-mount sling swivel, and does not fit my threaded, long-collar rifle. The dirtier stock has a bottom mount swivel, and does fit my rifle.
Both have serial numbers on the side of the butt.
In the interest of full disclosure, the only flaw with either stock is a small crack towards the upper front of the dirty stock, but it's still firmly held, and not in a high stress spot, and if desired, is an easy repair with some wood glue.
I just had some pics taken, including the crack, and the cross bars, hopefully I can get them to load up.
EDIT: I was having headaches trying to post pics here, so I just posted a fresh ad on my favorite statewide classified site, which i was going to do anyway, because my feedback establishes that I'm safe to deal with (and it's quick and easy to post pics there!).
