This is a pair of wooden desktop vintage mid century barometers.
The long one measures 7 inches long by 4 inches high and is made by Coles and marked Germany.
The triangular one is 5 inches high by 3 inches in width. It spins on the base and has pen holes on the top so it can be used as a caddy.
The smaller one is marked Linden also made in Germany.
There is some wear on the wood but not much and a little oxidation on the base of the long one but both are in relatively good vintage condition.
The instruments appear to be in good working order.
