Hi Jack.
Amazing project the one you have chosen. I believe you may find usefull the Frolich web site.
Mr. Frolich, built the Cyclope, under Boudriot's monograph.

He used the monograph of La Cygne, with the variant option of Le Cyclope. Figurehead included!!
I hope you'll find this useful.
Also, you can buy the Frolich's book, L'Art du Modelisme, wich has a chapter dedicated to this vessel.
Anything you need just ask me, send me a PM if you are interested, I have something you can find interesting.
Greetings.
Giorgio.
