Ball 25 J Auto TRAINMASTER MFG Dates
There were discussions on this site going back a few years about BALL 25 Jewel manufacturing dates.
I have recently acquired one with S/S case and 24 hour dial. I like to record the information on my collectives for the next caretaker, and so would like to try an nail down or come as close as possible at this time to establishing start manufacturing and finish mfg dates. Thanks for your time and attention..........Joe.........

That info Joe is going to be a big ask, mid 1960's is when they first started to appear on the Railroads to my knowledge. I do not think a production serial list even exists Frown
