GB machin study is a longtime interest, began in 1967 ... I subscribe to Douglas Myall's : Deegam Handbook CD ...
wanted GB machins 2011-06 .... will accept earlier lots to 1971. ... classic decimal ! (only recent NVIs) ...
in trade, I will send a pdf report of machins available... lots are fine used for phosphor study.
