French Patent 2,639,313 - Ofmega main image

Having followed the Shimano trend and butchered their Mistral design by hiding the bolt in the front knuckle (see French patent 2,628,383) Ofmega seem to have wanted to take the next step - to add a Shimano-style (or possibly more correctly Simplex-style) sprung top pivot. This is certainly what is described in this patent. Perhaps they dreamed of an indexed Mistral.

I don’t think this particular ‘improvement’ ever made it into production.
