John Neville is the wizard of the Sheetmetal, i'm just his minion, he might chime in but he's more active on MLU,we have the same thread running there which i'm basically duplicating as soon as he posts something new. Here is more UK centric and we figured we would potentially get more interest and useful information here than on MLU, John Isn't very active here though.
Thanks for your interest, folks I'm amazed that after going to Operation Market Garden 70th anniversary and declaring "I must have a Tilly", how quickly things have progressed (escalated? :nut:)
andrew, I shall email you shortly in regards to the measurements you want, we have an alternative proposition for you.
Cheers
Chris
