Heya everyone ! 
I’m currently working in my brother’s garage, and I found an engine with some of it’s pieces. Very rusty everywhere, but they are “intacts”
The differents parts are dispersed everywhere on the garage (including outdoor and the back-garage). For now, I found the water pump, the engine block, the pistons and the carburettor. Many pieces are missing…
Anyway, here is some pictures of the pistons :

Sorry for the quality, this picture have been taken with my phone at night…
