I hate to be a nay-sayer or to bring disappointment to anyone but to me, your Frankencord looks more like an Aires Reflex with a Rolleicord nameplate. I hasten to add that as much as I would like to be, I am no expert on Rolleis. It may be that there are other identifying marks, however, the photos I have looked at indicate that the closesest Rollei relative is the III model. However that has the shutter release and flash sockets reversed. The hood also does not appear correct - closer to the II model. On the other hand, the Frankencord is almost identical to a photo I have of an Aries Reflex except that has two sockets (X and M). The more basic Airesflex has a single socket and the body looks the same except for the lenses.
