Powermatic Varible Drill Press

Hello:
I just bought a heavy duty Powermatic Varible speed Drill Press at the ISU
sale. It's looks in excellant condition.
It says it's a model 1150, serial #66-7538-1. It has a Lima Electric Motor
model 4A, serial # P73476 JB.
The plate on the motor says it's a 3 phase 220.

#1 Can this motor be converted to 1 phase 220?

#2 Is there a 1 phase 220 motor that would replace this 3 phase motor?

#3 What is this worth?

#4 Is Powermatic in business still? I have never heard of them myself.

Please e-mail me off list with any help. Thanks
