the only thng that springs to my mind (other than a pipe bender ) is that could be the outer housing for some kind of control lever. Is the space between the 2 plates clear, only being attached at that cross pipe - can't tell from the photo's I'm afraid. If it's alloy and lightweight then chances are it's an aircraft.
In my limited experience, these random, out of context pieces can be very difficult to id. I posted some finds from Utah beach here back in April last year and despite extensive searches and enquiries, never managed to properly ID them other than they pprobably came from a US aircraft of some sort, possible, maybe a P-38
Found on utah beach: Aircraft parts? Identification needed
Indeed they are often very difficult to ID, especially when you have no idea what aircraft they may be from or what era. One thing I have learnt over the years though is to never give up ! I have lost count of how many times I've rushed to my 'Yet to be identified' crate of bits, to pull out a piece that I have suddenly discovered what it is
Never give up !
To me it looks a bit like the bottom of a control pedal bar, i think some were shaped like this with that heavier portion to the top
