For the true military train spotters amongst you I now have access to a set of List of Changes dating from 1888 to the 1950's. A very good research source for changes to most military stores and equipment. Should any of you know the reference and want a copy of the entry let me know. If you want some research in particular area then, for a modest fee, send me a message and I'll do my best. Thank you. I may even publish a random entry from time to time for your enjoyment.
