Once upon a time I had one of these little critters, the pre-Valoy II, the one with the wing-nut adjustment. Foolishly I lost track of it in a move.
If you have one, preferably complete, I am interested. As I am located in Europe, I will start out and see if I can get one here, just to save a bit on the customs and shipping expenses.
Any leads to one (as complete as possible) would also be helpful.
