It seems from looking at other Sea Trojans, there is a lot of room for "artistic licence"! Maybe not so much "artistic licence" as the changes made
during both the Trojan and the Griffin life of toil, after all they were launched in 1962. For example,and from some photographs I have, the Trojan has had at the very least three different types of boats, davits, a crane and at one time just a life raft container, never mind other fittings and probably colours, So you have plenty of choice for your final reproduction.
