Just to add to my previous post since I can't seem to find the edit function:
The Mosrite story was told to me by Rodger Wynfield from whom I got the Bluebird 6 that I still own. He was a guitar tech/part-time band member for Glen. He mentioned it when we were talking about the whereabouts of some of the Bluebirds.
In 1962 the Ventures paid Mosrite, to manufacture a line of guitars for them. That line's main guitar, for the most part, was The Ventures Model Mark I. The Ventures purchased these guitars from Mosrite and then distributed them. The Ventures were the sole distributor. This was a terrible deal for Semie and the Ventures...as it ended up that 100's of guitars sat warehoused and sold for pennies on the dollar when their 5 year contract ended and Mosrite went bankrupt.
In 1970 Semie started making guitars again and reintroduced the Mark I in 1971 and produced it until 1974.
It appears, that in 1985, Glen showed up at a couple of concerts playing a 71-74 Mark I.

The oddity is, Glen was fully committed to Ovation during the time span that this guitar was produced. It is no secret that Glen loved Mosrite guitars. Maybe Semie, once he re-opened the factory, sent him one. We will never know. But it is pretty neat to see a mature Glen killing it with a Mosrite!
