Most of the reports from Enfield are actually at Leeds Royal Armouries library; the contents of the original pattern room went there after Enfield closed and a short stay at Royal Ordnance Nottingham.
Up until August 1878 production of the IC1 C.C. was 25,000.
No carbines are recorded from the BSA and LSA companies (before 1890). however 150 are actually recorded to have been made by the National Arms and Ammunition company, in 1877, after their entry into the government contracts.. but I've never recorded one and these must rate as being highly desirable.
Between 1892 & 1894 the Henry Rifled Barrel & Engineering Company produced some 30,000 IC1 Cavalry carbines under full government view for the Indian forces and some 2000 Artillery carbines for the NSW government in Australia.
The BSA company records show they made MH Carbines in 1895 however their type and quantity is un recorded.
