-SG- We have I think mentioned before that Nortons did not supply vast numbers of military spec. machines during WW1. Seemingly most went to Imperial Russia and Juris has one of them - a Big Four - which is in danger of being back together in the not too distant future. Ian in UK has recently come up with a small 1918 booklet - scans attached - relating specifically to the 'Empire or Military Model B4.' I have never seen this rarity before - thanks!
