Hi all,
Whoops meant Mirage Hobby not Hobby Boss.
Sorry not seen a 1:350 type XXIII, I have the Skywave/Pitroad 1:700 version, it came with a type XXI which I needed for a diorama, don't panic IIRC it was a 2 piece model, just glue the hull halves together.
A suggestion, see if you can find a card model plan of a type XXIII and re-scale it. Some of the card models are very accurate, I've been toying with the idea of the ecardmodels type VIIc.
Regards
Jon
