Hi friends and neighbors,
today I drove to Deutsches Museum in Munich, last visit was 8 or 9 years ago. Again I found many interesting shipmodels, for example following sternwheeler, build 1926 in Hamburg for use on columbian (South America) river. Long time ago I wrote about the striking similarity with Krick`s "Mark Twain". Probable this is a dockyard model and later got the model for "Mark Twain"?

Hullo Thomas...at first I found it difficult to understand how the steam cylinder piston rod did not bend when extended :hammer
However it appears that the cylinder assembly has a parallel motion carrier rod mounted on the top of the cylinder
This then has a free floating sliding shoe to take the downward force moment and stop rod buckling ???
Is this how you see the connection?
PS.....there is also noticeable metal surface corrosion on parts of the model......so guess it is quite old [in years]

Yes, this is definitely a dockyard model of the Onze Nobiembre. And Krick used this easily and publicly accesible source to model their sternwheeler (very very roughly) after it. I always found it absolutely ridiculous to sell a model of a typical tropical steamboat under the nam of "Mark Twain", since it has absolutely no similarities with Missississippi boats. But to my shame and frustration, almost everyone here in germany inevitably associates paddlesteamers only with the Mississippi cliché, and apparently models are only merchandisable if the serve this stereotype...
Derek, no, what you se on top of the cylinder is definitely the valve gear. And these parts would also be way to flimsy to bear the lateral thrust of the crosshead!
No, the engine has a rather conventional crosshead which is running on slideways below and therefore hardly visible in the picture. But the engine is not very detailled in this model anyway.

yes, Moritz, it should be obviously a valve geared paddle engine in the tradition of the north american technic. See picture of Alan Bates "Steamboat Cyclopedium". But the kit of "Mark Twain" - from my sight it was a very interesting and nice model when it appears nearly 30 years ago.

OK ...& thankyou Moritz........this now is a better understanding....as the parallel motion rods appeared too light :shhh

Just some further pictures of Deutsches Museum, the sternwheeler "Charlotte Dundas" of 1802 and Henry Bell`s "Comet" of 1812. Last pictures are the fine model of "Augsburg" ex "Gisela" on Lake Ammersee 1893 - 1964.

Fulton`s "North River" of 1807; first German steamship, centerwheeler "Princessin Charlotte von Preussen" of 1816. First ocean going steamer "Savannah" of 1818. Engine temple - low pressure steamengine built by Ernst Alban 1851 for use in a factory.

One of the last few existing side lever engines. This one was built in 1841 for a Rhine paddler.

Wow! I must make a point to visit Munich again soon. :D
