Antique Singer Sewing Machine

My granny has an old Singer sewing machine built in the 30's or 40's in Britain. The cords are all melted and crispy and she asked me if I could get it working again.
She verified it worked years ago, but I'm leary on just replacing the cords.
The motor is stamped 100V - 110V DC and 25 - 75 cycles. I found a wiring diagram online and have the cord replacement down pat for the weird 3 pin plug, but I'm curious about the motor. I assume it will be fine running at 60Hz, but the DC marking threw me off. I've read online that sewing machines use a universal motor that can handle both AC or DC thrown at it, is this true?
From the pictures below, is there any reason I can't just replace the cords and call it a day? My worry is that there was no explanation given for the melted cords and I don't want to set it up to do that again.
Top picture is the motor, bottom is the foot pedal.

I'd replace the wires with something of at least #18 and call it a day.

If you are trying to keep the original look Google cloth covered power cords, Here is just one I found

The original cord may have looked "melted" due to biodegrading over the years as opposed to overheating from overcurrent long ago.

Wire it up with a modern cord (or a reproduction new original look cord. Then plug it in prepared to hurriedly unplug it. Operate the machine very briefly. If you think a malfunction is occurring then immediately unplug it and put a tag on the plug end of the cord stating that repairs are needed.

Yes there is a variety of "universal" AC/DC motors.

Back in the 1950's Singer advertised that genuine parts could be identified by the name "Simanco" if you were suspicious you were getting counterfeit parts.

If you guys aren't worried, I'm not.
Might make that my weekend project. Will let you know how it goes!

One thing I would be sure to do, though is install a grounded cord and ground any metal.

I thought of that too, but it would take some good macgyvering to bond the machine itself via the 3 pin plug.

How about feeding the power in via a cord wired to the machine, and using the 3 pin plug for only the pedal? Then you can ground the pedal, too if it's metal.

Thats too much macgyvering. I don't want to alter the machine at all, just the cord. I saw a picture online of a plug one guy added a small piece of metal to so that when the plug was inserted, the metal tab made contact with the machine frame. I may go that route.

Got her working!
Replaced the cord with some 18/2 and she fired right up.
So I'm going to assume this is indeed a universal motor.
Thanks for easing my mind on the cord guys!
