OK, the search is over
Picked up a F-Rib 330 and 15HP Mariner 2 stroke last night from a chap on the "other forum".
Really nice condition, and looks to have been well looked after so now need to start planning the maiden voyage.
Will pop up some pics when I get a chance to unpack.
Thanks to everyone for your assistance in the process - got there in the end
Cheers,
MM
