Hello KC
I thought I would receive an email when a reply has been posted (I'll have to double check my settings)
I have 'brass' in my post title - but "bronze" may be more accurate
several images attached - there are no actual marking on the piece itself
the only text is: FAHRENHEIT GLA & REAUMUR CE at the glass
0n a fun side note - the sliver mercury is accurate at showing the room's temperature
thank you for your detective work
