Vintage Machinery is my go to for this type of thing.
Look for details on the headstock such as the open pulleys and the fact that it is V-belt driven. Also the tailstock has a very specific form. Some are hollow, some have a closed face along the front. The feet on the bed are also good indicators. Note yours does not have holes/bosses visible for mounting it to the bench.
Hopefully someone else can be more specific and may even be able to identify it without a lengthy search.
