Wellsaw model 8 question

[cast iron]

Hi all, I just picked up an old Model 8 Wellsaw and would like to replace the 3 phase motor with a single phase, The tag on the motor is in bad shape and I can't find what the motor frame type is. I've visited the Wellsaw sight but have not found any info on motors. I do know the the motor on mine is a 1/2 hp Peerless but that's all I've been able to find. Have any of you replaced the motor on one of these saws? What motor did you use? Is there a motor out there with the correct mount? If all else fails I may use an inverter so I can keep the saw as mobile as possible. Thanks for your help.
