1957 Proctor Mark 6 Merlin Rocket, number 730 on EBay
Reluctantly nice old boat up for grabs to new caring keeper
If 1540 this is a Proctor XV.
FRom the look of the boat (Stern deck rolled side decks - very Wyche & Coppock of the time.) I would surmise that the sail number does not match the one on the thwart. The whole look suggests 730 is her sail no. So she is indeed a Wyche & Coppock built Proctor Mk6
Apologies I had thought to have revised the listing accordingly, as yes she is indeed 730, so have now changed it on EBay.
