bizzare relics found near ww2 beach (Scotland) and dump ID help needed

[brataccas]

Need help with identifying what all the items are. Not sure if all of them have anything to do with military but any ID would be a massive help. Found the bar with the V shape and hole on other side same place where I found the lancaster bathtub morse code tapper, Still no idea what it is also bigger things found as pictured. Biggest thing is from a vintage car?

Picture 7 is for overhead wire and on the threaded arms you would have a porcelain insulator, by the angle of the fixing bracket I would think it was fixed to the corner of a building, John.

Front Wing looks to be from a late 1930s car with pressed steel construction rather than sheet metal over wood frame used earlier - I could guess at Austin 10 or 12 post 1935 - but I am guessing! Pans don't look military, and the other large very rusty relic with handle looks like a large cylindrical petrol can. Group of three small cylindrical objects - two are dry cell batteries, Larger item looks to be an old radio component and if the photo lower down is the same object with "Dubilier" stamped on its base, this would seem to confirn this as this was a company that made electrical components.
