I knocked a few machines off my grail list of late, one of them is the 1938 Bernina 117 (Swiss made) which came here after WW2 and was owned by a seamstress.
It had been electrified but was originally a treadle machines so I mounted the old girl in an Italian parlour cabinet I had.
It is almost the same as their industrial version of the time... the bar on the front is a presser lift control.
