Sorry Barry, you're wrong! The PBM kit of Alfred was bread and butter principle, I know because it was the first scale boat I ever built! I now have the Tyne Models version, because I was so taken with the boat, the only trouble is being much larger, the Tyne version is a lot heavier, and I ain't getting any younger!!!
Pete, I do not have all the details, but I do still have the original plan by PBM. Let me know if you would like a copy, and I'll get it duplicated for you, and send it on, if you PM me with your home address.
