ID handle grips

[Ron Pier]

Thanks for the replies so far chaps. I have about 20 WW2 motorcycles in my collection and know of no use for Bakelite grips. The guy who has them seems to have quite a few and would like to identify them for ebay purposes. He is now going to send me a pair for closer scrutiny. He says they are not rubber, but either Bakelite or hard plastic and came with 2 tons of ex WD mostly motorcycle stock that he purchased some years ago.
I'll come back after they arrive. Ron

Here is a slightly better picture. They are indeed plastic or Bakelite and open at both ends. Adrian Barrel has had an educated guess at something for a turret controller. Ron
