Navigation at night?

No not that Tizer.

I’ll come clean in the morning if no one gets it before.

Calculating the days between the full moon?

It’s part of a large machine which used all the technological data incorporating the effect of the moon and other planetary information, but on what?

Tides?

Well done Kev.
It’s the Tide Prediction Machine constructed at Bidston. By the Second World War it had become a vital factor in planning seaboard landings

Woohoo!

That was a good one! Now try this.... what is it?

Is it a caulking tool?

Well done Gloria, specifically for driving in the finely divided lead wool that was the seal in old cast iron pipes.
Now we need another object!

This lubricator has a name. What is it? Clue, it's the manufacturer that made it.

No takers?

If there is no response by dinnertime I shall take this object down.

I’ve not a clue.

It's the Lunkenheimer lubricator of course!!

(I searched the site and found the last time it was a Mystery Object....no one came up with an answer back in 2022 either. )

Well done Wendy. Yes, In the late 19th century the American company Lunkenheimer led the world in lubricators. Their name became so well known that when they brought out this design for a force feed lubricator it immediately got called a Lunkenheimer.
Now we need another object!

What are we looking at?

The inside of the base of Rhodes chimney complete with internal lightning conductor?

Well done and exactly right. The biggest chimney base I ever got into. If I remember correctly it was 40 feet across.....
Now we need a new object!

Three inches in diameter. What is it?

Optical centre punch?

Dead right Kev, I was a bit optimistic with that one!
We need a new object!

I have no idea what this is, it’s not mine, does anyone know what it is used for?
