I think that ad should say “Portman” instead of “Postman”. It looks like a machine that was designed by the Portman Sewing Machine Company, and sold by National as a “Model J”, I believe....
I have one badged as a Montgomery Ward, and it’s called a “Model N-50” if I recall. My machine isn’t where I can get it out of the case and look at it right at the moment.
I removed the motor on mine in preparation for doing a little experimenting with treadling it in my MUTT. I thought the freearm would be great for darning (to mend denim jeans). I was fiddling with trying to treadle a Bernette 203 serger using the same treadle top (flat with just two belt holes in it), got hung up developing the serger application, and never even tried the Portman for treadling. Then, something else came up, and I never got back to either project....
