What is this thing?

[e-richard]

Help please. I need to find out:

a) what is this called ?
and then
b) where can one get a couple of them ?

It's a threaded retaining "nut" for holding down the hood and for holding in the folding windscreen on my 1937 (Opal) Tourer APE.

TIA

I think they are called acorn thumb screws - similar here: https://www.vintagecarparts.co.uk/produc...n-silencer

They are or were available from Willie McKenzie.

Yay. "Acorn" was the magic word that I was looking for, and I have also contacted Willie as suggested.

Many thanks for the quick and helpful replies so far.
