If there are no takers by dinner time I shall knock it on the head....
It is a hard one.

Can’t work out the size, but I’ll go for Manhole Cover

It's about three feet in diameter Cathy and you aren't a million miles from the answer. On the right track!

Is it from out of a steam engine?

Yes an essential part of a steam engine Gloria.

Is it an end plate for the tubes?

It's not for tubes but is part of the air pump....

I shall review it again at midday.

I don’t know.

It's very hard Gloria. It's the underside of the delivery plate that contains the valves that the water is delivered through. The bore you are looking up is the bore where the pump bucket works. You can see the groooves it has worn in the side over the years.



Here's an air pump delivery plate from the top....
Next one?

Good one, not in a month of Sundays would I have got that.

Thanks Gloria. Now try this one!



What is it? You've seen it before but from a different perspective....

No takers? You've seen it before.... (Funny how the hit rate drops when you can't Google the image!)
I'll review it at dinnertime.....

Ellenroad HP cylinder stripped down

Not exactly Tom but I shall give it you you are close enough. It's the front high pressure valve on the Bancroft engine. As I say, near enough and well remembered!

Can anyone give an explanation about this pic?

Germans trying to replicate the fall of the walls of Jerico

Russia's version of the US Patriot multiple anti-missile system. Also doubles up as an item for the Russian military band. In fact, Putin has just ordered military bands to the war front in Ukraine and that's not a joke - he's done it `to improve morale'. Honestly.

It's a German early aircraft detection system which works using audio.

Ian is correct, aircraft detection system.

Yes. I wasn’t sure if they were for real.
Aircraft Listening Machines, before WW2.

Gosh what contraptions they were.

We had the same thing on Romney Marsh Cathy but made of concrete. They focussed the sound on a central point and had a microphone there. We called them sound mirrors....

What's special about this picture?

Is it a daguerreotype image?

No, nothing to do with the pic itself - although it isn't the best quality! Concentrate on the object.
