Rajay Turbo?

I saw a set up yestreday that a guy brought over for my inspection. Never saw one before but i haven't seen many turbos or had much experience with em either. It was the pass side exhuast manifold with the turbo attached with two tubes attached, one was intake and the other ran to the carb. The other piece was the piece that goes over on the intake with two tubes fastened to it. It was used and he said it came off of a 440. His aking price is $1200 for the set up. He did have an oil line that tapped into the oil pan. The turbo spun ok but i thought it should have spun a little more freely. The tag on it said Rajay Industries in Long Beach, calif. Anyone know anything on em?
Wow, I did a search over on google and it looks like they are out of business but it also looks like the were a player at one time. Wondering now what they are worth and can they be rebuilt should it need work?
