Hej Thord,
The Keith Humber plans are very basic, and there are better plans.
Contact Mike Smart in England> He has plans made by Ralph Jackson of the 180, and these are very good plans.
The plans are for a bigger model, but can easily be reduced.
Mike has also plans for a 1/6 scale version, but I don't know what they are like. But ask him.
If you phone Mike, don't do it too early in the morning
Cheers,
shonny

Ah, by the way, I tried to get hold of Jack Stafford stuff, and that ended up in nothing. And according to some at the time, - just as well.
