That's a brilliant find. I hired two boats in the early 70's. One was Star premier, from Jack Powels , another was Water gypsy 2 birth i think, a very old boat even then but beautiful in every way. And finally a boat called Luck Stream,we got this from a boatyard on Oulton Broad,again a 2 birth.
If this broucher of yours has any of the above boats I would love to se them again
Kind regards
