do you have three phase at you place?
you have any more details on it , what voltage ,how old is it , the bearings good on it
and what size shaft on there , and does your buffing wheel supplier have the wheels for that size shaft ?
i don t really know the market value of it , but if it s in good condition and if you don t have to buy expensive electrical transformer to run it
and if you intend on doing some serious buffing work nthen this could be a good buy , i have one almost similar to that one it is very old ,i bought it used about 15 years ago for 350 $ back then , it is still running and never even needed any repairs , it easily spins a stack of 3x 14 inch airflex buffs .
if you are serious about buffing this will pay for itself in no time
