The first (Leica codeword TLCOO) was manufactured from 1936 to 1955 in minute quantities: only 679 were ever produced. It has a 39mm Leica thread-mount. This lens has five elements in four groups and takes 85mm filters. The second version (Leica codeword TLCOO, Leica catalogue number 11766) was produced from 1955 to 1966; 3360 of these were manufactured. It has four elements in three groups and takes either 91mm or 85mm filters. It also has the 39mm Leica thread mount. If the original poster will provide the serial number, I can probably be more precise in my identification. To my knowledge, a Leica thread-mount to Minolta BM has never been manufactured, but someone more knowledgeable may speak to that!
