Vintage Thermometer

Selling an antique scientific instrument, a "minimum thermometer". Displays well, especially due to the unusual double tip. All glass and metal construction. Holding tube is cardboard. Acrylic display stand included.

Lenght of thermometer = 28cm
Lenght of holding tube = 32cm

I've never checked if it's accurate, as I've only used it for display purposes. The room it sits in is a pretty constant temperature and it reads that temperature.

A minimum thermometer is a special type of thermometer for measuring the lowest value of temperature reached during an interval of time. The thermometer is mounted horizontally and when the alcohol contracts as the temperature drops, the alcohol meniscus drags the index.

Can be posted if someone is interested. However, I'd have to put quite a bit of packaging on it to protect it, so would need to check price for postage separately.
