I have several of these relays, NOS in boxes. The mounting is a bit like PO3000 but the mechanism is totally different. The markings are:
SER68/2A
768
3/402L
One of the coils is marked:
12 SCO 479
1700 ohms
3002 N
There is a single changeover contact. There are 2 knurled adjustment wheels. The 2 coils have separate connections on the tagblock.
Any ideas?
