Although the engine has different sized cylinders, it actually runs as a simple because Compounds are not reliable self starters without a Simpling valve. I actually cobbled two engines together, one 5/8ths.x 5/8ths. and one 1"x 1" which made for an interesting crankshaft, in order to get a self starting engine. Unfortunately most of the crew jump ship when it leaves the wharf so it runs a little short handed (4 channels)
The boiler is a pot type with water tubes, built and inspected under the code and sitting in an insulated steel shell, hence the rust. I tried to make the boiler and engine rooms appear more prototypical by including floor plates and laying them out according to accepted practice. To this end there is a two stage condenser, engine driven feed pump, and a separate donkey feed pump on the port side. Sounds good sitting at the wharf with the feed pump ticking over (weasing Weir's they were usually called)
It is fun to operate, although hard on the old back firing and tending to the auxiliaries. The boiler is naturally drafted with the high funnel (no suction fan required)and makes an abundance of steam, and smoke (smoke being the reason behind the whole thing)
