Whilst at Tony Green Steam Models on Sunday, I was looking at some of the items of the late Ian Stringer that they had for sale.

I saw these signals and I decided on an inpluse to buy them....

They have a nice brick base with a co-ax plug.

I guess these plugged into bases, but I couldn't see any.

Does anyone have any information on the manufacturer?

I am assuming these change aspect by reversing the supply polarity, so I will test later this week, but if anyone can share any knowledge on these, I'd be very grateful, thanks....
 
I tested one of these ground signals using a PP3 9V battery.

As suspected, they work on dc. Changing the polarity, changes the signal aspect between red and green.

I've yet to identify the coax connector, but it looks like a TV aerial type....

TV Coax connectors have a hollow centre-pin for the central conductor of the download from your aerial..

I would suspect they are more likely to be Phono plugs?

I think you are right Phil.

I seem to recall a version with mounting holes in each corner of a square base....

AKA RCA phono plugs and sockets.
The version with mounting holes may have been a "panel mount"
