I bought mine in England via UK Ebay.The company was called Middlesex group.They manufacture all kinds of Aerospace stuff.While I was there they had a helicopter roter forging sitting on the table, cost 75,000 pounds to make.They make stuff for Boeing,Westland,British Aerospace,Rolls Royce,Ford and many more .
I got my Studer for about 185ish dollars but it cost me about 4000 dollars to go pick it up.Looong story and don't want to hijack the OP's post.
The machine is still in London with my firend but I got the manual here, its got a lot of technical info and a couple of pics.Machine is complete and great condition albeit caked with grinding swarf.
The company had 2 identical machines, they threw 1 away into the skip (dumpster).That happened before I got there.1 of the employess listed the 2nd (the one I bought)on Ebay. I was aghast when I heard they threw the first one, they said it was taking space.They are concerned with productivity and spent 1.5 million pounds on machines in 2006 so this was nothing for them.
