The neck mounting plate makes one wonder: maybe Semie had a lot of them in stock from the time before the bankruptcy, and that was the reason he used them in Celebrities also? The Mosrite history is truly fascinating, and I think 1972 is a particularly interesting piece of it!
The neck mounting methods used on the Celebrities is interesting. The first ten produced, A0001 through A0010 were set neck. Next was the mortise and tenon joint held with two screws and ferrules. The neck end changed shape to be a more rectangular flat shape and they went to three screws with ferrules. I think they began having problems with the 12 strings and basses and finally went to four screws with ferrules by 1968. The kidney bean plate was used first on the solid bodied Mosrites and the Dobro had it in 1966. I've heard that when Semie got the name back in 1972 and started producing Mosrites again that it was a very scaled back operation. It would make sense to have a reduced inventory of parts and having all guitars take the kidney bean plate would eliminate the screw ferrules from the Celebrity. I don't know how many employees he had, but I was told that during the Jonas Ridge years he only had about 6 employees.
Interestingly, the original five prototype Celebrities were set necks and bolt on necks. My prototype has the mortise and tenon joint with two screws, Dr. Bill's prototype is the square end with 3 screws and ferrules. One of the prototypes was cut apart to see how the glue joints held up. The two remaining prototypes have not yet surfaced so I don't really know what their configuration is. I would guess that one is a set neck, the other...well who knows.
