A few dump bits to identify

Got these items from an old dump, not going to say where for obvious reasons, but lots of WW2 types broken up there. Some stuff is easy to identify as it has numbers such as hurricane and typhoon and the spitfire slipper tank plug. Others are too corroded. If you do recognise anything please shout out! There are lots of common electrical parts.
The second photo is what I think is the top of a Halifax throttle, it is marked GR-207.
