I forgot about the fancy stitches companion thread! I see a pretty close match on post #158 of that thread - it’s badged Dressmaker.
Unfortunately, these machines don’t have a lot of value to most people. The biggest determinant of value will be the condition of the machine (mechanical and cosmetic). Some people might like the “cool factor” of yours because it has all the knobs, etc. You might get more or less depending on your location. The color of yours might get more attention than most. It would be about finding the person that wants a machine like that.
If it sews, you might decide to keep it. These old girls are very durable and reliable.
