Machine Id Help

Can anyone help me identify this machine? Found on CL cheap, but no info is available.

Thanks

All I can see from the photo is that it's a straight stitch machine with a reverse lever and stitch length dial. The AC cord sticking out from the bottom is curious. Did the previous owner mount a home sewing machine motor onto the back of the machine?.Or is it just laying there by accident?

My guess is that this is a tailoring machine. A model number will help get more details about it and its cloth handling capabilities and speed.

FYI: Tailoring class machines are not meant to sew anything thicker than garment leather without sometimes major modifications.

Yes, there is a home sewing motor mounted to it. The seller claims that it was sold to horsemen to sew tack, and has a capacity of 1/2". Any idea if it's a walking foot or flat foot model? Seller can't locate a model number anywhere. I'm looking to use it for marine canvas and vinyl.

Thanks

It a Consew model 3115R & is very similar to a Singer 331K4 do a search for Singer 31-15 there is a lot of info on this site & internet about it.Not the best machine for canvas because it doesn't have a walking foot.It won't sew near 1/2" leather or anything else! I'll bet this person used to be a used car salesman.LOL Probably why the horseman got rid of it.

The seller is fibbing. That is a garment sewing machine with a flat foot. It may lift high enough to sew 1/4" or so of cloth, but not leather tack. It will not allow the use of heavy nylon thread either.

It will probably sew vinyl and canvas with #69 thread, maximum. But, due to its only having bottom feed, via feed dogs, it will slip if the length or weight of the material is greater than its ability to secure it. The solution to this would be to first replace the feed dog and throat plate with a heavy duty tooth set, then crank down the foot pressure spring to prevent unwanted slippage.

Most marine and awning sewing is performed on walking foot machines. You may want to look into a Consew 206RB-5 instead. It has compound (triple) feed and can sew up to 3/8 inch of material, with up to #138 bonded thread.

A word of caution about using a HH machine's motor with an industrial machine: you will burn the conventional pedal regulator with anything heavier than light textiles.

I tried doing that and burned it as soon as we tried to stitch jeans. The motor was fine, just the pedal has burnt its resistors. The electronic pedals may be fine though.
