My findings were, that we have made a total of 947 best double rifles, in various calibre's since 1900. Perhaps it doesn't sound a lot, but it is 3 times more than the 300 odd that Purdey have made and I don't know how many compared to Holland & Holland. 947 rifles would take a craftsman about 350 years to make, so that puts it into some form of context! We have made doubles in 51 different calibre's.
I am sure these numbers will be of interest to many of you who own one of our doubles and I will make a point of making the information available to anyone who wants to ask. In brief though for now, the 5 best selling calibre since 1900 in order, calibre/quantity are: 1st. .470/109, 2nd. .500/104, 3rd .577/85, & .318/85, 4th. .400/74, 5th. .450/69.
