Stormy

On the first day of Summer my mother gave me Granddad’s old barometer. A crash course in how to read it will ensue. Also an investigation in how old it is. It is of German origin.
I did note as we drove home from Murray Bridge the needle moved slightly as we went up to the top of Mt Lofty Ranges. I think that’s a good sign.
I think it may need a little TLC.

Extra: the device itself
