Ofmega Mistral front derailleur braze-on type

Some new Ofmega Mistral parts to complete the Mistral group set for my road bike project.
I already have all shifting components and a crank set.
Because I'm considering a frame set with a braze-on fitting for the front derailleur, I had to look for another front deraileur. and this was not so easy to find.
But thanks to  good friend, here it is!
