Want to Buy LTB SKS Factory 10rnd box mag

Recently picked up a really good shape Norinco SKS, seems extremely low round count put through it. Just spent day one with it cleaning out the chinese cosmoline from the internals. original owner seems to have removed the original box mag and replaced it with two 35rnd Promag Duckbill mags (did they make 35 rounders? it fits 35 rounds...) Guy i got it from bought it from the original owner and stored it for years, never shot it themself. Looking to put the 10 rounder box back on. Chinese or Norinco make preferred in good+ shape. looking to spend 70-100$, but show me what you have. May consider even doing partial trade with the current 30rnd (35rnd?) mags I have with it. Gentleman said he likely has 2 more mags, not sure if they are the same promags, though. Pay method via Paypal G&S please. Thanks for looking.
