Does someone have an unembossed Montreal they can show next to a "normal" unembossed 143?
I've aquired an unembossed 143, MOLD, with a wire goove similar in size and position to those on my CanPac slugs and Montreals.
This comes from a retired linesman who worked for Bell and took it down himself in the early 70's.
Thanks,
Chris
