Bonjour,
Clapboard mahogany launch built on the basis of MRB plan "The Seagull", length 1.40 m, width 0.40 m, weight about 15 kg, Babcock boiler (to be checked) without safety valve nor manometer and without gas tank, recovered as you can see her of an estate. The Stuart D10 seems functional and not seized but does not work with the few hundred grams of pressure of my little compressor.
I will probably add Stephenson slide valves to have a reverse.
