Large original Schatz Brass Ships Wheel Compensated Precision Barometer 13"

Description

This is a Large original Schatz Brass Ships Wheel Compensated Precision Barometer. In total it measures 13" or 33 cm in diameter.
The barometer itself measures just over 6.3/4" or 17 cm in diameter.
Its protrude is just over 4" or 10 cm.
It is in EXCELLENT WORKING Condition.
The only thing I need to mention is that one of the spokes of the Ships wheel is a little loose. I have shown this in the pictures.
