Thanks Mike,
The props are Raboesch, from Cornwall Model Boat Supplies in the UK..
The struts, etc are styrene and glued onto the styrene sheet that is laminated to the brass strip base.
The styrene strip is CA glued onto the brass. Thin styrene cement for the styrene on styrene. All seems pretty solid so far. Haven't had a brass/styrene failure yet and the styrene cement is like liquid soldering.
