Now having a break from really complex keys, time to make a relatively simple yet hopefully precision key, 074 and 075 have used a sort of cylinder construction which I rather like and which has produced a serious machine like action in this one, its a real Greyhound of a key, the knob can be either a flat finger type or an upright wooden variety, either seems to work well on this design, working on it has given me some more ideas for yet another straight key :) And it is my very first attempt at Nickel Plating, I take my hat off to all metal platers it is not easy :))
