#298903477 has the TRZ furniture marking that is desirable among Yugo collectors. The finish looks good, I would ask about the receiver # and if it matches the bolt, floor plate, and stock. He was pic's of those matching #'s but no pic of the receiver that I saw.
$250 is a tad high, my 24/47 cost $265 with three tins (1400+ rds) of ammo and a Mojo sight still in the package, been a while ago
After looking at GB prices maybe $250 is about right.
