French Patent 2,639,313 - Ofmega main image

Having followed the Shimano trend and butchered their Mistral design by hiding the bolt in the p-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 b-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.
