[GreenKeys] OT!: telephone switching question

[Eugene Hertz]

Sorry for the off topic bandwidth.

In my junk box, I found a *really* neat device. I believe it is from a phone switching system. The unit has 2 relays and a semi-circular set of 10 contacts with an arm that connects to an incrementing set of contacts with each dc pulse given to the relay. There is another relay for resetting the arm back to "home".  Has 3 wires, one is common, one steps the relay and the third resets back to home.

The only designations I see on this unit are:
CRY 29982
K-105
A-22751

I am looking to to a little project that will require 10 more of these and an old rotary dial from a telephone.  Any chance someone out there has 10 of these stepper relays and an old rotary dial? 

Thanks and again, sorry for the bandwidth on this off topic topic
