Try this one. What exactly are these?

Do they open manholes (or person holes).

I can see why you thought that Cathy but sorry, no.

Are they different forms of steps? I'm thinking of those you would drive into tree trunks or telegraph poles.

Sorry China but no. Again, I can see why that thought struck you.

Are they attachments to an anvil which help produce circular sheet metal objects?

For sticking in an anvil, not heavy enough for blacksmith or sheet metal work so I'll suggest silver smith tools.

Oh dear P! You have put me in a quandary here. You're thinking straight but you have the wrong conclusion. Too heavy for a silver smith. Have another think....

Tinsmiths formers?

For producing sheet metal objects? Possibly tins.

Or aluminium?

Ian has it. It's a selection of tinsmith's anvils. Different shapes for different jobs. They weren't for putting in the Hardy hole in an anvil but in a hole on a block of wood. Many of the tinsmiths were itinerant and a block of wood was light enough to go in the handcart.
Next one?

What's the common name for this configuration of chassis?

Let me think!!

I think I know.

I've always referred to it as a 'twin-steer'.

That's correct Kev but there was another more interesting description.

Are you looking for a humorous jargon name or a technical name?

Chinese six?

Kev has it. Chinese Six. Eight wheeler rigid was an Eight-legger, the trailer was a Pup.
Next one?

Any ideas on what is going on here?

Is it a potato clamp? Not sure about the scarecrow!

Curses! Her serene majesty has done it again. Quite right, old technology and I thought it would be a forgotten corner.
Back to the drawing board Stan[ey!

Sorry! Been there, done that..... without the scarecrow!

I'll try again. What can you tell me about this image?
