happily sailed into scapa flow as brit sub with no friendly fire ..great stuff..

allso changed the typeIIA sub interior model to the type7 and it worked perfectly as normal...typeII exterior and bridge (bit of a shame that as i was hoping the brideg was part of the interior modelling as this might have made using a destroyer external model with a sub interior a lot easier with an eye on a surface ship mod)

BUT the type II withe a type 7 interior worked perfectly..
just changed that data/submarine/NNS-UboatII cfg entry
to

[Unit]
ClassName=SSTypeIIA
HumanPlayable=YES
Interior=data/Interior/NSS_Uboat7/NSS_Uboat7
UnitType=200
MaxSpeed=13.0
MaxSpeedSubmerged=6.9
Length=40.9
Width=4.1
RenownAwarded=110


it occurs to me that the type XXI slowed down to type 7 speeds and specs with the type 7 interior would make a reasonable Russian sub model...or even a Jap sub model fancy that me self a Jap campaign would be highly unusual..

allso allows me to get round that bug on the type 9's interiors (in the un-patched game) where the dang lights flash on and off all the time by substituting in the type 7 interior..
