Exactly right. Now we need another object.

What is it?

It looks like a piece of garlic sausage with ideas beyond its station in life.....

nay. A more practical object.

A weather cover for some sort of roof vent

As soon as Cathy mentioned roof I saw the ridge tiles. It's a ventilator tile that sits on a ridge tile.

It is indeed, it's on the kitchen roof at Chez Kev. It has the vent pipe, from the cooker extractor, in it. Well done Cathy

What is it and where?

You've seen it before. Think Scotland, West Coast..... History.

The Massacre Cave on Eigg?

Well done Kev, yes
Now set us our next object?

Can anyone remember what this battery was used for?

A torch?

Front bicycle lamp?

Oooh Wendy, I think you may be right.

It brings back memories Gloria!

Wendy is right, it's a bicycle lamp battery.
I shall go for a furtle.

Here's another specialised battery. What was this for?

I would say its to power a vintage portable valved radio.

Not exactly Ian but I am giving it to you. At one time the early valve sets needed two sources of power. The low tension was supplied by a single lead/acid cell and the high tension was supplied by a dry battery with multiple tappings for adjustment. This gave up to 120V.
Now we need another object.....

What is it?

No Takers?

Haven’t a clue.
