Hi ya Martin
I was supplied with the original plans for the Vosper; Brave Borderer; and it has all of the correct frame shapes. Also, it has the table of 'offsets' - this table gives the correct dimensions for all of the frames. So anyone with a large enough backgarden and a few hundred grand to spare will have a go at building the lifesize hull - hey Vosper might have something to say though eh ???
On a serious note, comparing the drawing with the model; and, comparing Tamiya's model to the drawings there is no noticible difference. The only difference that I can see is Tamiya model has a twin rudder and the plans show three rudders.
As far as the wooden kits for the Brave Borderer are concerned; these were flat sided and kept as simple as possible for the plywood build. If you have a look at Martin13s build, the flare on the bow and on the sides is correct.
