There isn't a list of decode names but your BUQ Which might be a very old machine. I believe (don't know for sure) TL is Timken Bering in Headstock with unit L with V Belt not Flat belt (a K !!). Find out if the belting is in V's or is a large flat belt. I think the K is the belt not the model. Model is on nameplate on front of machine. The 10" lathes have a simple Apron assembly while I have a complex with friction and gearing. "Carriage unit K-119 might be yours does not have a dial for threading. The 10" does. The 10" has a compound on top as well. The Motor Drive unit is a double cone in mine, while the "U" drive has control handles for preset speeds. That is the basic stuff. There is a nice website in the UK that has machines of all sorts and lets you do a picture and id check that way. Many documents. Good luck - Martin
