Please Help with correcting river class

[Mush Martin]

First thanks to serge and neon for their answers to my initial enquiries

I have noticed that sometime in the research porition of the process somebody
got a river class destroyer mixed in with the river class frigate data.

now recognizing the difference may not matter to most
but a river class frigate looks essentially like a black swan
but with the following differences

4" d/p in A turret replaced by hedgehog
4" d'p in C turret replaced by 3" single
aft radar stand moved between main mast and bridge
aft deckhouse reversed so bandstands are aft
remove 4 K guns
Reduce AA suite
now I am still learning to mod and havent yet changed a ship other than to put
a type VII Conning tower on a type IX and swap out some guns, but I would like to correct the rivers can anybody leave me a list of what I need to change when I swapped cfg files for Black Swan and River class the boat changed but the stats in museum etc were all Black swan also I need to know How to change out the guns or remove them assumably in the roster files. as for moving radar and reversing deckhouse I havent any idea where to begin. finally If I do fix it I would like to pack it up and make it available. As the river may be the most underated ship of the Atlantic Campaign.

any help or guidance would be appreciated
with thanks Mush.
