The deed of agreement between James the younger(who ran the firm from 1858, son of James the founder) and his sons, James (also called James the younger on the family tree?) and Athol, which resulted in the change of name to Purdey and sons, was signed on the 21st Dec 1877 (from, Purdey's the guns and the family. By Richard Beaumont.) a fascinating insight into the history of the famous firm.
So as orry rightly says above, 1878, presumably after the Christmas break.
I doubt the information in the book is incorrect but i found the James the younger part confusing. It would appear that the father of James and Athol was around until 1909.
I'm sure the book is easier to understand than my ramblings though.
