Hi John, nice looking model.
Would agree most things can be fixed with a bit more filler, however one has to weigh the cost of that amount of filler. lol. Super stucture apart, its the bulkheads that will need altering to allow where the slope on the hull is for torpedoes.
Just saved the plans so can have a look and see if I'm right about the forward bulk heads. If not then will have to sort something with Glynn to use his plans.
Will have a look at you album.
