After checking out the links,I think I have everything I might need to do one. The only major problem I see is that all the drawings and photos are different in detail. In addition,there was to be a "command boat" included in the three boat kite or attack group. More to the point, that spring loaded frame is the first detonator and I'm not sure it would be found on the command boat

? One thing I am sure of is that this was duty for the politically incorrect .... !!!!! I've also found different descriptions of just how the attack worked,too. It seems that the crew were to jump out of the boat about 2000 m from the target and swim home or back to the command boat

? Another version had the crew section detach and go home under it's own power. There were several kinds of boats of this kind some unmanned others manned. More on this later after I dig in my spares box........
