Hello ibex94,
Yes indeed there are many old machines here. There were several Singer factories in Europe. In France, Italy, Germany and the biggest was in England. You can still find a lot of them. I am looking for information on a particular model but I can't attach a photo. I wrote to the site administrator to try to find a solution, I am waiting for his response.
In the meantime I created a link to show the machine:

This is a 237M faired, in two hulls that I have never seen elsewhere, I have no information on this machine which seems to be an unusual model. Usually the 237 have an engine fixed at the rear on the frame when there is an engine. This model has an internal engine.
