Oak framed barometer - not working (CT7)

I rescued this in a sorry state, dumped by a bin and covered in paint. I’ve cleaned it up, the thermometer is working but the barometer casing is cracked so that isn’t (it’s set on Fair) Does anyone want it for decoration or a prop (or can even replace the barometer part?) Ot seems a shame for something so lovely and almost 100 years old to go to landfill
