Who am I?

This cute little badly-neglected spinning wheel has come to live at my house. It is in pretty rough shape, but I think I can get it working with a hefty bit of TLC. Someone has left it out in the rain, but happily the wheel is not warped.
I've never seen one like it. In most ways it looks like a home-built, but the orifice and a few other bits look commercial. Anybody out there recognize the maker? It is double-drive, the flyer whorl screws onto the spindle, and the mother-of-all is hinged to flop to the side (similar to an Ashford Traveler).
