Not a clue Stanley

I forgot to look Gloria. The object is a bronze segment that was part of a Universal Metallic Packing on the piston rod of a steam engine. They stopped leakage but didn't wear the rod like normal packing in a stuffing box would.
Now we need another object!

What is it?

A large cotter pin?

Correct Ian. Well done!
Now we need another object....

What is it?

No takers? These used to be a very common domestic item.....

It's a dolly blue bag!

Spot on! Well done Wendy.... The earlier ones had a wooden post in the middle to hold while you swirled it in the rinse water.....
Now we need another object!

Which trade used this tool?

Farriers, to deal with clinches.

Straight in there! Yes Gloria, I forgot you were a horse woman!
Can we have another object?

What is special about this flagpole?

Can it be moved about?

No Gloria, it's a permanent fixture at Anfield football ground.....

It's from the SS Great Eastern?

That was the accepted story for a long time but now there is another narrative, that it came from the royal yacht Alexandra. (LINK)
However you have it right so now we need another object.

What is it?

Some type of key?

Almost but not quite. You've seen it before, it's textile trade related.

Is it for threading the yarn through the shuttle eye once wound, (instead of sucking it through)?

That looks like a military pose for the photo, and there was a fashion once for cool instructors to add a grenade pin to the zip on their uniform jackets - but nowt to do with the textile trade so I give up.

That made me smile - having worked in Liverpool for four years - they can't even agree which ship it was nicked from. Must have been a challenge to get it out of the dock gates. Rely on your stereotypes - they don't come from nowhere.

Sorry, not for threading shuttles. More repetitive than that and warp related, not weft.
