I have the Lionel CCII Sharks and they are really good looking engines. The problem is they don't represent a particular model, and definitely not the RF16 as advertised. The body and fuel tanks represent the early (pre Jan 1950) DR4-4-1500, but there are post Jan 1950 DR4-4-1500/RF16 details like the horn and pilot mounted sand filler. It also has the right side nose ladder that was added to all sharks around 1960. The cab numbers are also for the last two RF16s built.
I have been thinking about what needs to be done to the Lionel Shark to make it a pre-1950 DR4-4-1500 to fit into my layout's late 40s era. Change the multi-horn to a single horn, remove the ladder, file down the pilot mounted sand filler and change the cab numbers. That should do it.
UPDATED to correct previous statement on the nose ladder.
