While finishing off a French 64 I did a bit of digging and found with a simple re-flag and a change in the insert we can have some more 64s from SGN109c

If you happy to use the flip side here which is HMS Argonaut

British Caton Class
Hms Argonaut. French ship Le Jason
Hms Caton. French ship Le Caton

Both brits were captured French ships
