INFO FIXING my boom vange Jeanneau 45'' Sun Kiss/ 1986

I would be happy to get info about the company brand of boom vang of my sailing boat :JEANNEAU sun kiss 45’’ / 1986.
There is no brand name on it and I have to fix it and get some parts and drawing.

A photo might help people identify the brand. The photos of Sun Kiss boats for sale on Yachtworld at the moment all show vangs with simple tackles - no rigid vangs. A likely supplier for rigid vangs might have been Goiot or Seldèn. Also, since it’s French, try searching using the term “hale-bas” - the French word for boom vang.
