Just looking only, “Hanimex Praktica 66”is very similar to “PENTACONSIX” and “PENTACONSIX TL”. But, “Hanimex Praktica 66” has the 2-synch sockets for X and FP with cable stoppers.
2-synch sockets is the feature of “Praktisix Ⅱ”. But, cable-stopper is not provided in those. The fact that it can provide cable-stopper is from “PENTACONSIX”. But, Synch socket is one in “PENTACONSIX”.
From this, I think that, “Hanimex Praktica 66” is not the mere OEM product, which has sufficient feature.
But, “Hanimex Praktica 66” seems that is the very short-lived camera. In 1971 June edition and the July edition of “Modern Photography”, it has appeared in announcement of publication camera shop “Cambridge”, but with the October edition it has change the name to “Pentaconsix TL66”.
