Hi,
Does anyone know what screw size was used in fitting the head to a First war 60Pdr Shrapnel streamlined model.
Technical drawings of the day that I've found so far show 'Screw, A8, twisting pin B8.
Are these military designations for a standard Whitworth type of screw? If so what size is that screw?....
Many thanks in advance!
