MYSTERY OBJECTS

[Mags]

Dad, I have slept since then.........

[Stanley]

That's funny, I can remember as if it was yesterday. So we know it's in a tunnel. I'll give it until dinner time to see whether anyone can come up with the answer.

[Stanley]

When the second of the first twin tunnels at Standedge were built (LINK) it was linked at the half way mark by a cross tunnel which had cast iron vaulting and encaustic tiling flooring. The directors held a banquet there and the image is of the cast iron vaulting. Margaret was with me when we walked to the half way point as part of the activities of the Hebden Bridge Gay Gricing Society in 1978......
Next object?

[Stanley]

What are we looking at?

PS. Meaning of 'Grice'. To collect objects or visit places connected with railways.

[Steeplejerk]

Hole in a wall

[PanBiker]

Entrance to a pothole?

[Stanley]

Clue, it's man-made.....

[Stanley]

Another clue..... It's the highest in the UK.

[Stanley]

One last clue. It's closely associated with the last object......

[Steeplejerk]

Hole in a tunnel vent

[Stanley]

Sorry Tom but no. I shall give it until dinner time and then reveal all.
(Read the Wikipedia entry for the railway tunnels again, it might give you a clue!)

[Stanley]

When the first Standedge railway tunnel was dug they made short cross shafts into the existing canal tunnel and used them for extracting spoil material via the canal. This is one of the cross shafts and you are looking into the canal tunnel.

Who can explain this? I reckon most of us are of an age to know.

[Stanley]

Van Goch minus one ear so one plug monaural. Bach deaf so no sound at all, don't recognise the last one. That's as far as I can get.....

[Big Kev]

I'll give you that, yellow plug is composite video and red is right audio. Van Gogh missing his left ear.
Second one is Beethoven, completely deaf so video only.
Third one is Stevie Wonder, blind so right and left audio only

[Stanley]

Bloody hell! That's a surprise.....

[Stanley]

What was this image used to advertise?

[Mags]

Playing Cards

[Stanley]

Sorry Margaret but no. It was an industrial product.

[Big Kev]

Abrasives?

[Stanley]

Yes! Specifically?

[Mags]

Carborundum

this is why I said playing cards.

[Stanley]

And that's why you got it exactly right Margaret. She beat you to it Kev!
Now we need another object.

[Stanley]

There is a specific name for it. What is it?
