This snare is a good (but not perfect) example of Pearl's "Jupiter" chrome on brass (COB) snares, produced in the late 70's to early 80's. "Jupiters" had a parallel strainer system ("0-16") installed on the heavy shell. Pearl also produced a model on the same shell with a Gladstone type strainer ("0-15"). This particular snare has triple flange hoops installed; I can't be sure if they are original or not (it appears that the snares could be purchased with either triple flange or diecast hoops). Also it appears the original muffler is long gone and was replaced with an aftermarket version, so I will soon be scouring eBay and elsewhere for a muffler of that vintage. And I'll be keeping my eyes open for the 6.5x14 version of this drum. There are two sets of 8 wire snares on this. Puresound produces a "vintage" set of wires for Jupiter snares that are one set of 16 wires.
I've also attached catalog pages from 1979 (which shows this snare) and from 1983 (by then the parallel strainer system was the "017" system, as on the other Pearl parallel strainer snares on this blog. The '79 catalog refers to the Jupiter snare as the "B4814", but I have also seen reference to it as the "B4514".
