Yes, Jurgen, this is the boat of de Joffroy. In the next "Journal für Dampf- und Heißluft" in january there will come out one article about steamboating at river Rhone with excurs to the boats of Claude de Joffroy. The boat model in Paris is the ancestor of our live steam models. There must be one topic by me about de Joffroy in "Research" last year, when I remember correct.

Regards Thomas

I tried to read as much as possible from the shown pages and in the Fultons Folly article you mention Claude Jouffroy's early ships.
I think I have a picture of the model which is displayed in the Paris Maritime Museum. Unfortunately I don't have descriptions of the pictures I took more than 10 years ago, but when you mention that he used a ratchet mechanism instead of a crankshaft I thought that this may be the model.
Also very interesting is the "feathering" mechanism, in particular when this was built in the 1700s.

Thanks Damien.

Slow, slow, slow progress and some disasters to report here.
I made the stern grating, painted the funnel and spilled some paint.

The stern grating work went without mayor difficulties and looks OK to me.

Small disaster: During the painting of the funnel some of the blue paint did not pass the masking-tape-test when I had masked that part for painting the black top and lower cone.
I tried to mask off the cone to repaint just the blue part but that turned out to be very complicated and I could not get a straight line. So I opted to raise the black part and paint the damaged part black.
I am happy with the outcome.

Big disaster: When prepping the wheels with my precious zinc-chromate primer I managed to tip over the paint can and spill most of the paint.  It is precious because I use very little and was able to purchase a 1/4 liter can a few years ago - still was 3/4 full. Now no one sells any broken quantities any more and I will have to buy 1 liter. At the speed I am using this primer that will last for over 100 years.
Anyway see the pictures.
Fortunately no feathering paddlewheels were harmed in this incident.
