Where is Mirko the number one expert in Marklin steam Engines to tell us more about these large engines, and their characteristics?

An absolutely amazing engine. Most of the patina was just dried oil by the look of it. :shock:
Right. It doesn't seem to have much patina.
The nickel wipes clean with an oily rag.
I have not polished any of it.
There is a sort of dried once oily haze on the boiler and chimney. Since the chimney is half rusted anyway, I tested cleaning it with acetone. It required some rubbing and left a nice blue finish. (No longer yellowed)

Good question... Are you out there, Mirko?
I am interested in learning more.
For example does anyone know the bore sizes?

Here is a video of the 2nd air test. I cleaned up the sight glass and fixed a couple leaks and have a couple left to attend to.
I think it would be prudent to put a thinner belt on it as this one seems heavy and adds drag.
Does anyone know what the original belt was like?

Runs good..... Gil
Be very careful with the finish on the base, it's very easily damaged....
The belt does look heavy. Not sure what they used ?
I see the little lamp is just hanging there.... that's good no holes were drilled.

I am watching this thread with great interest.
But i cannot tell you anything new about this engine.
It is simply too big and too rare for me. I am better in telling you something about the smaller and more common engines.
Anyway, i believe the belt was a thin leather belt that was glued and/or sewed together.
That thick belt is 100% wrong and far too thick...

Thanks, Mirko. For the near future I will make a short cloth belt.
Then I could order a length of the PM Research belting material which is woven with a black rubber or silicon coating.
This can be glued or sewed.

Would it be acceptable to touch up the paint where there are scratches on the base or to add some missing paint back to the dynamo?
Without killing the value?

You better don't do that!
Has no great sense, it is better to leave it as is.
One tip: you can take gun blueing to touch up lost paint on the base.
(if it appears too shiney, the metal beneath) Otherwise any touch up would decrease its value (a collector also might think: if THIS has been touched up, what ELSE might be wrong on this engine?") ________________________________________

Hi Gil, I would leave it the way it is. It is almost a 100 years old. The original paint is oven heat treated, and it is impossible to recreate the little white freckled paint. I also noticed that you pressed the cylinders cover a little while cleaning, but this can be fixed easily.
