Very interesting in that this engine has two totally separate boiler / engine systems with no pressure equalizing crossover, so they are only tied together by being on the same crankshaft!

I may well agree with Scott's recommendation, and even second the motion, but first I'm going to have to decipher whatever the heck the second half of his acronym means .... guess I need to brush up on my code breaking skills!?!?

In any case, that was one fine video production you have provided for us here Charlie .... Well Done!!!

Thank you Daniel.  In the video, I pulled one of the burners to see how it would run.  As you can see, it only ran for a few more seconds on a single burner.  This version of the Model 340 is very different than the 4 Doll Double Boilers that Oliv showcased in one of his videos.  Mine only has one flywheel and one whistle.  and his 4 have a connecting steam pipe between the two boilers.
