It's interesting to read that the 974 was advertised as a fine watch for electric street railways, as well as railroads not maintaining time requirements! Regards. Mark

Great Items! I always look forward to seeing all of your items, they are wonderful.

Items even better than the "book" sometimes, for someone trying to learn a watch.

Seeing the original product is somehow easier for me to remember, and if I don't, I have a great source to see it.

Thank you for all your hard work.
