Chinon Twin
The Chinon CM-7 is quite an obvious derivative of the CT1 Super, aside from the altered shape of a few plastic moldings. Both are SLRs using the popular Pentax K-mount bayonet. The Ricoh KR-5 Super II really ought to be in this comparison as well.
Note that this particular Chinon has had a replacement of its rewind crank, which originally was an exact match for the CT1 Super.
