I know exactly what you're saying John. It's us Brits talking a foreign language to you wild colonial and antipodean foreigners.....or is that the other way round? But it's confusing for Armourers (and there are a few more Armourers than you think read these threads.....) who can't understand what a king screw is or the top band.

Anyway, I hope that Capt Johns querie has been answered, by those foreign chaps in Englandicon!
