I'm pretty sure I've got a manual that states how to switch the motor from AC to DC - and yes, the same motor will work for both. Remember, these came out before electricity was standardized in this country (with AC winning) so for a while, depending on your supplier, you may have AC or DC in your home. What I've got says to contact you supplier to ask which you have.

I also have an odd-duck modified 27. It has the godzilla finish and is missing the singer emblem. I'm pretty sure that Singer had a standard that if a store modified the machine, they were suppose to take off the emblem as it was no longer factory specs.

Very nice machine.

watcha say we wait until the OP replies before we run much further with this.....

OK....

...but once we get the serial number, won't that take the fun out of guessing?

A lot of suggestions from members, and valid concern about this Singer machine, which are shared.

The purchase price was very low so, not much help in valuing present value;

Will re-check the numbers and see;

The cabinet is what it is, whatever its provenance, no way to know if it's just a mixture of different aged parts?

Have to get back with some answers, thanks for your interest..

well dang, that was quick!!!

My White Rotary Treadle was electrified too when I first got it. The motor was quickly removed (still in the garage, I believe) and all the treadle parts were intact. Wondering why someone would bother to remove them to add the motor and electric bits? Seems like a lot of extra work and makes the treadle base look awkward. The base in the op pic is the same base that came with the 66 I bought for my sister for $5. The machine date was 1925.

Sorry - mis-post!

If it's a127, then it's a run of the mill machine in the basic treadle cabinet that is missing parts. In my area, it would be worth $50- $100, and that is if you get someone that is uniformed willing to part with a lot of money.

It's like about the cheapest machine and cabinet one could get from Singer at the time, and since then it's been modified quite a bit. So it's not really worth anything to a collector, only someone that likes it and wants to sew with it. It should be very good as a usable machine.

BTW- if they arleady had the table and wanted electric - why not remove the treadle? I'm sure at the time the owner thought it was just a piece of old "technology" and would have never guessed that some day, near 100 years in the future, someone would want a treadle machine! And I know first hand it's a pain to try to sew with the electric pedal on top of the treadle pedal, even if you wire the treadle so it can't move.

This cabinet looks exactly like the treadle machine my Mother and Father bought in 1923 with the $12. they had left after getting married. (They already had a "Homestead" here in Oregon) I also learned to sew on this machine. Do not remember the model number but it did have a long bobbin.
