Wow Gil, this plant is just marvelous. An engine that commands respect and interest worldwide. I am looking forward to a video .
Thanks, Kenneth. I hope to be able to make a nice video of it under steam.
After clean up, I will lubricate and air test it. If all goes well, live steam will be in order. Compounds really prefer live steam and a work load.

Ron, how about a picture of the whole engine. If I remember right it is quite a good sized vertical Marklin and a real nice looking one at that.

It might be a rare version, but it is faulty. Marklin had to change the design and reverse the cylinders after discovering that running the steam supply pipe for a longer distance without any insulation was causing the high pressure cylinder to choke and knock because the steam was condensing into water before it gets to the high pressure cylinder.
Honestly, I beg to differ here. I own a few engines whose steam pipes are not much shorter and running well...
However, my experience with my own Marklin compound (which is the latest, i.e. cheapest, edition and in such a sorry state that I do not hesitate to run it once in a while...) shows that these compounds do have a problem: the oilers of the second, low-pressure cylinder invite you to oil it as deliberately as the first cylinder - but we shouldn't forget that these cylinders are linked directly!
Thus the gooey steam/water/oil emulsion of the high-pressure cylinder is directly transported into the second cylinder only to find some additional high-viscosity steam oil there.
No wonder these compounds tend to choke...
A case of "less is more"...
 
And again - an absolutely lovely dream engine you have found there! Was it advertised anywhere or a case of sheer serendipity that you found it???
And is it rearly the large 11cm boiler??? You should rent a safe box at a local bank in that case...

Gill: You mentioned pictures of my large Marklin Vertical.
This is also somewhat of a Monster. I do have a small line shaft to install also need a pump and Gov.

Hi Ron,
 
Lovely vertical Marklin you've got there. I have an extra original complete Marklin governor that I placed somewhere that might fit your engine. If you are interested, I will look for it and can bring it with me to the next Cabin Fever and see if it fits.
