Hello Gord-C!
I am also creating a Mississippi sternwheeler.
There I was also looking for ideas. Here are a few of them, and if you have some patience, I can show you my version. Am just drawing up in CAD . . Will get back to you later.
Hobbyist greetings Michel-Cl.

All these photos have either received or found on the Internet. These are filed with me under the folder : Ideas from around the world . . . . Thanks to the Internet!
