Rocket-man, In my many Hrs spent with Ken Hunt both sitting Harry Kells old wooden chair in the Old Broadwick St W/Shop.and on my Trips Back to "Merrie Olde" England, Ken had many pages of handwritten pages of Kells Timesheets....But alas like the sand through the egg-timer,most have been lost.If memory serves, McItosh & self wrote a 2 Part artical on the Kell Dynasty in Shooting Sportsman and we mentioned some of the times that were taken for engraving jobs...I do have in my "Olde-Stuff" a handwritten note to Kell from someone at,I think Purdeys,saying "My Man will return in(A very short time) to pick-up the Matched Pair of Guns, and the Monograms will be finished in the Gold Ovals!......Try that to-day!!!!!CC/dt
