This sewing machine is called a Diplomat. Its a brand I do not know very well, I suspect that it may have originated from India, I think that it was made during the sixties and was most likly a version of the Janome label. There is something interesting, why I think it may have come from India, is that it has a very long stitch length, up to stitch length four. This is often the case with machines doing embroidery top stiching , popular in India. Would like to know more about it.
