I have 3 Zoli 58s. A 2 band Zouave, A Hunter carbine and a JP Murray. The serial number on my Murray is 16475, or 60 digits higher than yours. I bought it new in 1973 for about $250 from Navy Arms. NA still offers them, don't know who makes them. In the replica business, the tooling seems to get passsed around a lot. Looking up value under NA for the Murray:

Grading 100% 98% 90% 80%
MSR $705 $625 $495 $395 $295
I'm usually guided by the thought that it's worth what someone will pay for it.
