For Bing 10/110/1 circa 1928.
Manometer
Safety valve
Wooden handle for whistle.
Smokestack with water tank part way up chimney - Base diameter is 34 mm and I think it may be around 300 mm in height. A plain chimney would be fine as I could fabricate the water tank
I do have a spare poppet valve engine, 109 /110mm flywheel diameter that is available as an exchange if it helps.
Thank you
Stuart
Poppet valve engine no longer available
