+1 for Internal Fire. I've visited several times, very enthusiastic team of volunteers. Large stationary internal combustion engines, several running each time I visited, and a willingness to start up any of interest (I suppose if they are not too big). Last time I went, they had a steam engine they intended to get running.
Also, some mid-century radio and telecoms equipment. I also had a quick view of their workshop; about as tidy as mine, but producing somewhat larger work.
I moved from Surrey to Somerset, then Wales. It definitely gets wetter as you go west! Bore da, all.
