AC187: English Spring Letter Balance

Date: c1930s

Size: Approx. 3 1/4 inches by 2 inches by 3 3/4 inches.

An english metal spring letter balance dating probably to around the 1930s and made by M. M & S Limited.  It has a good spring action and works well, though I am not sure if it is still very accurate.  It is in excellent condition with no damage noted.
