i happened to see one on ebay. photos showed what appeared to be a screw mount of appropriate size. google search did not turn up anything definitive. my helios 44-2 in m42 is a dandy little lens, but because it is preset, does not get much work on my pentax sp1000 when i have an auto super takumar 55/2. a helios in LTM would be a great choice for an fsu or bessa. preset obviously woulkd not be an issue ... 🙂
