Identification of Electrical Item

It is indeed a pickup unit for power to a loco or car. I've used these with GREAT effect on my MDC Shay as they fit nicely behind the side-frames on the trucks, and the wire is almost invisible as it rubs the back of the wheels.
 
Hello Dragon, Would you be willing to post a photo showing one of these installed? I am certain that several of us would be very interested in seeing how this works.
 
Today I received a reply from Precision Scale Co. regarding these items. Here's their reply:

The are #4898 and #4066, both of which have been discontinued.

Yes, Precision Scale is here in MT. Stevensville, to be exact. Stevensville is in western MT, north of Hamilton and south of Missoula. Oh well, so much for trying to keep up with things in MT. I see from a previous post that they moved to Victor. That's about a five mile move. We're such a fast movin' state. Expectin' to get telephones here any time now.
