Good work Eifion! You've captured the atmosphere and feel of the engine room well and your diorama has a lot of atmosphere - bet it brings back a lot of memories for you.
It sure does some good some bad. I was very young on them old steam up and downers before moving on to motor ships. I miss my former ship mates that most are now long gone , a special breed of men. We lived hard and played hard in those days in ways that would be frowned upon these days
