This is an original antique barometer by H.J Hatch in Gt. Yarmouth. It has a porcelain dial and the frame body is cast iron metal. It has a metal hand. The porcelain dial is loose and needs to be secured. It no longer has the glass covering. This can be replaced or leave it as it is. It is still a very beautiful barometer. It is very heavy for it's size and is very well made. It measures 8 inches in diameter and 3 1/2 inches in depth.
