Got this Miranda Focabell bellows system just this week, found on eBay.
Manufactured by Miranda Camera Co., this is an early 70’s type 7 (AIII) bellows with wheel locks, serial number 633605. Condition is very good, except that the two small screws holding the lens bracket to the front slider were loose, allowing the lens to move sideways. I had to detach the bellows and the front bayonet to reach those screws…
The first so-and-so test photo; that’s the “M” from a Miranda viewfinder prism:
