All T-adapters consist of two parts, an outer ring which has the camera's mount and an inner ring which contains the 42mm T-thread. These two rings are held in place by three equilaterally arranged screws. Loosen the screws and the two rings can be separated. The same basic arrangement connects the M42 mount to the Russian lens. Take the M42 ring off the MTO, disassemble a T-adapter, and put the mounting ring onto the MTO. Tighten the screws, and, voila! The original MTO's as sold by Spiratone had true T-mounts, and there was a small family of lenses produced in the late 1960's which had permanently affixed M39 or M42 mounts, both in M42 registration. But, since 1970 or so, all lenses have been as described above. Three ARE three versions of the 500mm MTO, the f/8, the f/6.3, and the f/5.6. To my knowledge, the latter two are identical, the difference simply being one of accomodating either Stolze or International markings. The 4.5/300 sounds interesting, but I've never seen one on this side of the Atlantic. Marc Marc James Small Cha Robh Bas Fir, Gun Ghras Fir! FAX: +540/343-7315
