Large Index Box containing data cards of British Railways Midland Region Locomotives in the range 42050 - 42984. An incredible record of these locomotives with each card having the type, number, building date, allocations and withdrawal details. They carry a stamp generally dated various months in 1950 and the details are typed. Looks to be complete but not guaranteed so. Some photographs accompany. We aren't quite sure whether these are official or not but either way, a superb, dtailed account of the history of every loco in this range. Must be seen to be appreciated.
