I'd have to say...
That's the shiniest Tradition I've ever seen! I did the same with an Omega, replaced the bearings 22 years ago and with weekly use,it's still going strong. Looks like you'll be doing the same with a Classic III, nice, very showy.
I've seen a few Classic III's where the little "belt view" window on the nozzle is either scratched missing or scorched.This is usually caused by allowing a lot of string, yarn and hair to accumulate on the belt pulley and it begins to rub against the window.
I doubt that you or any collector would ever run their machines in that condition,but just wanted to toss that out for info. Bill
