They look like tap reseating tools to me, Mal.

It's a re-seating tool for water taps. The brass bodied kind of tap with a rubber washer.

All together now chaps!

They are valve seat cutters, the tapered threaded part screws into different size valve holes inorder to make it more adaptable.

Beaten to it!

I'm pretty sure it is for doing dental work on elephants.

(could be wrong, the plumbers above could be right)

Sphincter surfacing tool 😀

I once machined down the diameter of the cutter to use as a spot face cutter for spot facing the opposite side of a base mounting hole on one of my model engines , a bit fiddly but it worked !

Similar ones used for removing piles ?

Last two posts are a load of ‘excrement’!

Any more anal ideas?

I have a random bound volume of about WW1 vintage, of Model Engineer. In it, one correspondent describes how he re-cut his kitchen tap seat.

Essentially he made something like a Keats Angle-plate from wood and bolts, to hold the lower half of the tap on his lathe face-plate.

Obviously he cannot have had a Mystery Tool, Taps, Domestic, for the Re-seating of.

The taps of his day were simple bib-cocks whose upper half could be unscrewed from only just above the seating. He probably had only one, cold, tap - and possibly in the whole house, not just on the scullery's porcelain sink - so not worth the cost of a Mystery Tool, ditto, when he already had a lathe.
