What do you need to know about them? I believe there are a couple of sets. One is the original Neil Fowler design. The other is a more recent (90's) version. They are both for plywood construction. There is also a set of instructions (or a building guide - I think written by Philip Pearce) that comes with the plans.

If you want to buy a set, contact Philip Warren-Smith. His details are on the VMCA contacts page.
