Please bear in mind the signals may not match the box. I have lots of items and trying to match them is quite a challenge. The box details are:
Hornby Dublo Signals – Single Arm (upper quadrant) D1 32130
Which seems to match the signals inside, but what you see in the pic is what you will get. There are no electrical components here, these are cosmetic, hand-operated signals - as far as I can tell.
I hope that's clear and honest, as is the picture of the tear on the side of the box.
Lots of other OO gauge items listed, well worth a look. Cheers.
