Taken from Church Street

What sort of light is this and how old?

What does the letters on the walls mean?

BRB is British Railways Board which only existed between 1962 and 2001

The railway bridge lettering is a bridge indentifier code. DD is quite right, BRB = British Railways Board. If you use this link, you'll see that CCS1 relates to Rock Ferry-Woodside.

Regarding the lamp, it looks a bit like the ones MD&HB used on the docks. It would have had a large wattage incandecent lamp in moons ago.

This is the land at the back of the swinging arm is it not?

The lamp looks like a REVO C12421/C12422 or C12423 series, missing it's glass bowl.

See: All sorts of street lighting stuff here

If so, it probably dates anywhere from the late 1930s to the late 50s.

It's next to its car park.

Sad really if the lamp is all that's left of a once busy area

Where's the Swinging Arms on this pic?

Here's an birds eye from Bing. Sadly I can't match it any better to the original aerial:

Swinging Arm is at the "bow" of the biggest dock wall, the bow wall is still present.

Derek's picture is pretty close to how that area is now.

Might help - best I can do: old pic, today pic (Google Earth), and merged.

DD is this the wall (how far down would it go)?
Wonder what will become of that land - maybe not safe to build on but would make a nice camping site maybe
billy_anorak59 I couldn't make out the overlay pics too well(a noble effort), so am just happy to use the 2 pics posted with the pub marked

That looks like the one, you can see the bow wall of the dock on this picture.

We'll put it down as an epic fail then!
Worth a go, never mind.

OK, I'll give it another go (God loves a trier) - is this the lamp then? Or is this another one like it?
(I hope it resizes all right)

never noticed the far lamp - it looks as if it may be intact
Next time I take my grandson to the playground may try to get a better pic of it
