Teledyne magnetic latching relays and Teradyne I/O Series Backplane/Connectors

[dentaku]

For those of you who don't already watch Fran Blanche's videos, she's working on a project that needs some old parts that are difficult to get in volume at any reasonable price.
I thought I'd post this here in case some old Greybeards might know more about these parts.

In this follow up video to a much longer one she explains what she's looking for.

TELEDYNE Series 420/422 Magnetic-Latching TO-5 DPDT relays http://www.teledynerelays.com/electromechanical/420422.asp
and
TERADYNE I/O 100 Series Backplane/Connectors with 120mil spacing
They are shown in the video I linked to.
