Good for you Oz as the Gunny's here could use some extra dosh as in W.A our turn around for additions is having our shops on the verge of extinction and any work they can get helps them survive if you have a 0000's dollars of ordered weapons sitting there waiting for the Contractors to check your paper work not the local police station as was the way in the old days. There are plenty of old 303's that could use a new tube and to have some finals done to the new tube would aid our ailing gunnies and ensure the job in done safely and not a back yarder.
PL why did not say Lithgow, Maltby, Faz, L B and so on go with indexing marks was this used as a guide to the U.S.
A Amourer's so they could measure the amount that has to be machined etc to align the marks to speed up the process or were their tolerances so much tighter than the Commonwealths speaking on the '03's of course.
TIA
