The Miele brand was originally manufactured by Guvin Co, Ltd. of Mississauga, Ontario, Canada. The brand is named after the founder, Jim Miele, who emigrated to Canada from Italy, as a teenager. The company fell on hard times in the early 1990s and the company folded. The brand name was sold to Procycle in 2002, a year before Jim passed away. There is no connection to the German company.

If you want some decals for your repainted Miele, I still have a small supply of original decals. I don't think I have the model name decal, but I can supply just about everything else.
By the way, some of the original colour schemes for the Binova were red to white fade, lilac to white fade and violet to white fade. If one of these turns your cranks (pun intended) you may want to keep closer to the original.
