And it lives in a drop dead beautiful house!
You're a lucky guy indeed!
Thanks! It was a lucky find and it's in pretty much mint condition. It cost me all of 30 GBP.
I was frankly amazed to find a Weston cell for sale on eBay and even more surprised that the seller had no qualms about posting it from the UK to Sweden. (I certainly wasn't going to lecture him about the legality of shipping a package of distinctly harmful substances by air mail and cut myself out of the purchase!) I was quite apprehensive when I went to collect it from my local postal agent. I had visions of seeing a soaking wet package and having to reluctantly advise the guy behind the counter that he would need to close his shop and call in a hazmat team to decontaminate the place while he was at the hospital being decontaminated himself!

Thankfully, it somehow survived the trip and after some silver polish on the terminals to remove the black oxidation and wiping down the case with a damp microfibre cloth, it was restored to its original glory. Chemically, I expected the cell to survive the trip without trouble as Muirhead incorporated a porous polythene disc in each arm of the H to keep the various chemicals in place, even during transport upside down.
I have no idea where it came from and sadly the seller didn't have the original calibration certificate. It has certainly never been abused and while it's no LTZ1000, it does seem to develop the expected EMF once adjusted for temperature, so it's still useful as an ultra low noise sanity check in the absence of a recently calibrated standard.
