In 1882 when Chamberlain took over the Cook business it was of course still in Shepton Mallet and not Andover.This means that the latest date for the manufacture of the gun under review would be 1883.Following the relocation of the business to Andover, Hampshire,the name was changed to Chamberlain. By virtue of the patent date of 1870 we can say that the gun under review was made between 1870 and 1883. The Thomas patent enjoyed only limited success,it is therefore likely the gun was made early in the 1870,s.
Note:Boothroyd records;" Edward Chamberlain at Winchester Street,Andover, Hampshire Circa 1900."
