Original “balance weight” for Isetta, Trojan etc for sale!
From an eBay listing in the UK, the seller’s description:
Here for sale is an original gold painted BALANCE WEIGHT for a 1950s TROJAN and BMW Isetta Bubble Car. These were apparently used under the passenger seat when there was only one occupant in order to stabilise the car round corners. Marvellous and probably incredibly rare. Weighs about 15 kgs.
While it is heavy it is not what this lump of metal was used for. Can you guess what it was originally used for?
Hint: it *COULD* have been used in an Isetta or Trojan!

I believe it was used for entering a locked vehicle if the keys were misplaced. The idea was to throw it into a side window to gain access to the door latch.
I have also heard that it could be used for an auxiliary parking brake.
Very rare piece.

It actually has a function. Just not the fantastic one the seller describes.
This can augment a certain system on these microcars that was rather feeble.
It was probably NOT something that US drivers would use, but would be more well known to British drivers of the day.
