Miriam,
Looks to be one of the Singer 400W series. It's may or may not be a walking foot machine. The 400W machines were not walking feet, but the 402W machines were. It has a double rotary thread take up, not the traditional take-up arm.
Many Juki industrials had that style take-up. I have a household White brand with this Juki style take-up. Its a strange animal, but a smooth sewer.

This one is interesting. I'm wondering if it is some kind of needle feed - tension must be on the end - looks heavy for sure.
