I have not, you think that serial number off the cross head data tag would work? I did end up finding 3 prints that are similar. They have a K relay for doors closed anyway, the terminals are all C3, C4, etc but maybe if I ignore the C. My problem is simple, there are no relays picked in the controller except the alarm bell relay when you push a hall button so probably safe, door locks, or gate. This may be enough to go back with but I’d feel a lot better with a print that matched. I thought maybe Montgomery had put their name on another manufacturer’s controller that someone might recognize. I’ve seen US IBM relay controllers that Montgomery painted dark grey and put their name on.
