I have ordered one of the Monahan horizontal boilers, and plan to mate it to the Heron engine I already have in my possession. Once I get everything set up as a bench test unit, I will post some images and a YouTube video as well. Plans are to do a comparison review of several marine steam engines I own (MH Caton/Anton Crystal/Monahan Heron).
In the mean time I've attached a photo of my Heron engine on the shelf of my shop, neatly nestled between an MH&B boiler and Anton Crystal engine. The boiler and Anton Crystal are slated for installation in the Topaz kit I recently started....those are the polished boiler bands in the foreground awaiting completion of the wood boiler lagging for steam plant assembly to begin.
