Oh My....an Error... I forgot to point out that the James Purdey Pair Nos. 10614-10615 that were delivered to Mr Hunt by James Purdey, The Younger',on January 1st 1880. Were of course Barreled with The "New Whitworth Fluid Pressed Steel". We think that they are the First "Pair" Built using 'Sir Joe W' Steel. cc/dt
