Antonia Engine - Marshall valve gear
Posted: Wed Jan 26, 2022 4:02 pm
I found a steamboater in Germany who has posted a few videos of his Steam Launch Antonia.
The engine looks like it was machined and fabricated custom for this launch.
I was wondering if anyone can identify the valve gear, or perhaps describe the operation of this engine.

At the 2 minute mark in the following video the throttle and reversing lever are moved and you can see how this engine responds:

P.S. I am also posting this because this steamboater's youtube channel has less then 10 subscribers as of this writing, I'm sure he would appreciate a little more attention because he obviously put a lot of effort into putting this launch together.
