No problem. Just curious because your question came up just when that NP58 listing appeared so I thought your OP was related.
These NP58s are not available from dealers today, and when they were last available early last year at $349.00, they were snapped up quickly. As well, Norinco magazines were 35 bucks each when they were available. Canadaammo sold their NP58s with 2 mags, Marstar with one. New Sig (Mecgar) mags from some CGN dealers are around 50 bucks.
Few NP58s ever come up, well at least I hardly ever see them, on the EE.
My NP58 came in a trade package last September, and was valued by myself at 300 bucks, with 50 shots fired and one magazine.
