    2" GS thread gauge...

    Hello all,

    Despite searching the site, I haven't been able to find a thread discussing WW1 2" GS thread sizes, which I stumbled across ages ago, for British 18Pdrs, 8", 9.2" etc.
    I know the thread is a 2" GS (1.906"-1.912") diameter with 14 TPI but does anyone know what the screw pitch is?

    Also, to take it further, does anyone know of a company that produces a tap for this size?
    Thanks in advance!
