I know H & R used to sell 1/1200 parts and Triang used to sell parts for Triang ships, but they are both gone.
Anyone know of companies that sell parts, like guns, directors, missile launchers etc?
I have recently discovered that 1/700 parts can be modified and used: example: 76 MM for 5"54, BPMS (seasparrow) for ACROC and the GMLS works as is.
Hope it helps and look forward to hearing your ideas.
