WTB: Blackwell Average Speed Calculator

[Mark Morrissey]

I suppose this is as long of a longshot and there could be but I've become daring in my advancing years.
I need/want a Blackwell Average Speed Calculator for a story I'm working on.
This is a plastic, circular rally calculator.

If you have one and if it's NOT for sale, perhaps you'd allow me to borrow it to photograph.

Thanks very much.

Mark, if no one on here has one, you could try the facebook group 'The Golden Years of Rallying'. There are plenty of the 'older generation' on there who will have one
