There is a 1939 (??) "Macomber" loom on Ebay. The castle looks like a Macomber, but the rest doesn't. It seems to have a fly shuttle on the front, and you can see the typical jacks on one side (who knows what's on the other side) but the frame is very different. So, is this a model I've not seen before, or did someone take a Macomber and modify it - a lot?
Here is the listing:
