Wanted : Barrel / pistons for 650cc Huntmaster FH, 1957

[Glyn.Ford]

Hello.

I need a set of Barrel, nice if with matching pistons for a 1957 Huntmaster FH, 650cc. Mine has a broken fin and coller, and currently has +40 pistons. It is marked with "PAT NO 567029" on the front, and "H", "U" and "IMC" on the bottom.

Open to the idea of re-lineing and new standard size pistons?

Many thanks.
