Old tool challenge

[YankeePorker]

Virtual pint for the first PHer to identify what this old tool was used for.

Tyre pressures?

Next challenge, how do I make the images post the right way up from my iPad...

[YankeePorker]

Nope, not tyre pressures.

The tool comes from the BSA factory.

I think you’ve got it, but can you be more specific?

[alorotom]

Tread depth gauge?

[Dabooka]

Something to do with calibre checking? If it’s from BSA?

[YankeePorker]

Paint thickness ....

Should have a little magnet that will extend the spring dependant on the surface giving you a reading.

Bingo

Though I was never sure if it was for paint or chrome thickness measurement.

My dad was in the building trade all his life, one of the most fascinating little tools he ever showed me

[YankeePorker]

Well done, way too fast, thought it might be obscure enough to confuddle people.

My grandfather bought it as a piece of memorabilia at a bike autojumble 35 odd years ago, and it’s been travelling with me ever since, never used in anger.

Not much use for that if he was a bricklayer?
