Sabine,
That's a nice machine. The only difference between the BelAir and the SEWMOR is the decals I think.
Here's a pic of my SEWMOR 303:

It's not a great pic, but it's the only one I have for now.
As for the 404 currently on GW I wonder what in the world they did to freeze up a machine as simple as that. I've already go two of that model, a black one and a silver one, so that one can wait for someone else to adopt it.
