LOT of 20 FUJITSU SPDT Mercury Wetted RELAY's - FMR-874D10/1CS -- New and Unused

Description

One Lot 20 Mercury Wetted SPDT RELAY's.  Made by FUJITSU, part number: FMR-874D10/1CS.
New and Unused old stock parts from the original styrofoam trays.
Metal Sealed, Mercury Wetted contacts.
Although the parts are UNUSED, the finish on the metal cases have a "tarnished" or "patina" appearance.
I could not locate any spec sheet so don't know the contact ratings but have tested their operation
and they appear to be +5V coil types with 330-ohm coil resistance.  Thus the following seem correct:
Contacts are SPDT
Coil Resistance ~ 330-ohm
Coil Current ~ 15mA @ 5V
Coil Power ~ 76mW @ 5V
Can
Dimensions
(slightly flanged at bottom) are ~1.8" x 0.51" x 0.4" high (excluding leads).
Leads are ~0.17" long (there are 5 leads total).
Note: As with other Mercury RELAY's i have seen, this one should likely be mounted vertically (say, +/- 30-degrees) for proper operation.
And there is an UP ARROW on the case to indicate that is likely the case as well.
I will try to keep the parts in their original styrofoam tray =but= might possibly transfer the parts to plastic bags depending on which is easiest
(cheapest) to ship - parts should not be harmed at all.
Will ship in a USPS 1st class priority Flat Rate padded Envelope or Small/Medium/Large Flat Rate box, depending on the quantity.
