Another nice video Dave,
The J series were very good, Here is the J80 I owned a few years ago, OTA and rings only with a vixen RA finder, this is what got me interested in Pentax scopes, optics were very very good, best I had experienced in an 80mm scope, I have also owned a late1950's Jupiter that I restored again great optics, this now resides in a museum in Spain,

I have two of these J80 scopes - one is a very early serial number in great shape and the other has a few more "miles" on it, including a small clamshell chip in the objective. The second mount is also somewhat incomplete, but could be a good source for parts.
In terms of other classic Pentax gear, I also have the small black J60c (quite different from the J60) that is an interesting little package. Plus I was lucky enough to obtain a vintage ep set (two orthos and a kellner) that used to accompany their long ED scopes. It is a bit of a mishmash of a collection, but I have always had "a thing" for Pentax astro gear.
