AT601860 - Could I make some sort of coin and fee checking set ?

ATW 601860 or ATC 601860

On bob's site Ive found them to be LOCAL CALL TIMING CIRCUIT FOR USE WITH FIRST OR SECOND SELECTORS. POSITIVE BATTERY METERING NON DIRECTOR EXCHS 2000 TYPE

Its relays are

PA FR

LM RD

H

RR ( the cam thing)

The Cam thing (RR)is marked REL 1B/001/24 1/23A 310 Ohm

There are Two disks one with 3 notches and two normally open contacts

and one with three anti notches (if there is such a thing) has one normally closed contact and one changeover contact

There is also a contact that breaks when the relay is energised.
