Way to go Phos! That's a nice '57 Romanian! And with the correct Romanian sling, to boot! You did great and I'm even a little encouraged that there may be one out there for me, yet. Congrats!
That looks like one of the Norinco made bipods in the first pic. Did it come with the carbine? I have a couple of the Norinco bipods, but they used a thick coat of black paint on them instead of a good parkerizing, bluing, or Moly coating of some sort. I'm going to disassemble one, strip the paint, and put a good finish on it, (which finish?...yet to be decided on). I like that bipod for bench shooting. I used some self adhesive felt on the inside of the barrel clamping jaws to avoid marring the surface/finish of the barrel. It worked quite well.
