What will happen to your collection when you are gone?

I'll see what happens when I take it to him. I'd imagine he will have a few barometers around the shop so I'll just ask him to set it the same as those by eye. It'll only take a couple of drops and I would do it myself but mercury isn't easy to get hold of and I have got an online shop that sells it but it's like £35 for a small pot which is probably still more than I need so It's probably best I get it looked at properly and see if he'll do it for a reasonable price.

 

Take care how you transport it...

The first link didn't work but the second one was interesting to read. Here's a couple of pics of mine, It's also a fairly local one which is nice to find. The eagle eyed amongst may notice that the wall paper has been re-done since the last time I took a photo on the dining room table.

 

That's rather nice and I would definately look at getting it restored..

Hopefully this link will... http://www.npl.co.uk/reference/faqs/how-do-i-transport-my-mercury-barometer-(faq-pressure)

Yours is a different type though and there may be specific instructions for transportation.

For anyone within a few miles of Tedington you can use this http://resource.npl.co.uk/pressure/pressure.html to calibrate your barometer. The best time to do this is on a calm day when there are very few isobars on the weather map. Use the sea level reading and set your barometer to that unless you specifically want to record your "station readings", in which case you will need to know your height above sea level and do a bit of maths to find the correct setting.
