Hello!
My husband and I got a little excited and purchased this beauty at auction without realizing the complications of 3-phase power source. We tested the machine at the factory we hauled it out of, so know it works, however there isn't much else we know about it. We hate to see this machine just rot in the garage while we attempt to figure out how to power it. We don't want to change the motor to single phase and potentially ruin its usability. Would love to see it go to someone who can put it to use, we all know these workhorses will go on.
Here's what we do know:
Singer Sewing Machine, Model 7-31, Serial Number AF653437, Consew Clutch Motor, 0.5 HP, Power 220 Volts / 3 Phase, Reverse pedal
After searching through some of the advice and guidance on here, looks like the heads for these can go for upwards of $1.5k. Make us a reasonable offer.
Thank you for your time!
