Model
76. This one
breaks in half with speakers in one and amp and speakers in the other.

I found another one on Ebay:

I bought a 76 case without the amp. Let me know if you have a chassis that you
want to sell - or I may just let my case go cheap.
This one is a Twin
88. Very strange configuration. It breaks in half like the 76 but it
has some kind of bizarre key arrangement to control tone. Here's pictures of
one:

Several of these have appeared lately on eBay:

Here's another Ebay auction.
