Here is another Sterling tube tester from the early 1930s.  This is their model 407.  This unit looks like it tests 4 pin tubes like the 201A and 199 and other tubes of the 1920s battery radios.  It is untested but looks to be in good condition.  On the back side is a set of instructions.  It measures about 9" X 7" X 3".
