John - I didn't realise that you had a Unitron 4"!
What a fabulous looking machine that is. What year is yours?
There's one going on eBay at the moment - and should fetch a good price as it is in pretty good condition.

(or if that doesn't work, it's eBay item number 250038370299 )
I suppose you've seen the site dedicated to the restoration of one?

Do you use it at all?
Cheers
Chris
