A question for Mr. Laidler

I wonder if you were ever able to discover the meaning of the letters "AF" which are sometimes found on the side of the Inglis?
Thanks, Jim

To date, no. But missed an opportunity to ask a load of very old time Armourers several weeks ago. But I will find out as it was marked on UK Military pistols although I never saw it.

Will plough on until I find it......................
