First let me say thanks for a great forum, it's been a great help to me finding info and helping me decide to take the plunge with this great old machine, I haven't run a lathe in thirty years but have wanted one for a very long time, I tinker with old hit n miss engines, tractors and do some amateur gunsmithing, and love all things old and American made so this old lathe will fit in just fine, from what I have gathered from the forum is I have a 9c Ser. # 51739NCR10 Cat No. CL615 maybe Z can't really tell, seems pretty complete with the motor and back mounted pulley assembly, little three jaw chuck, beds in good shape, spindle is tight, it runs, very workable I believe after a real good cleaning, I gave 200.00 for it which I though was a tad much but after driving two and a half hours I figured I could at least get my money back if I decided I didn't want to mess with it after I got it home, no change gears came with it, bummer, now I would eventually like to be able to cut threads but my first priority is to get everything cleaned and inspected and oiling properly before I run it anymore, one question I have is this machine has the spring loaded knob on the reverse lever and the gears look a bit worn, are these and the whole gear train for that matter the same as the older style reverse tumbler ? When shopping for gears are all the 9" ABandCs gears interchangeable ? Please pardon my rambling and thanks in advance, Dave
