[Heathkit] meter question

[Michael Tortorella]

Greetings all: in the endless cleanup of the basement storage, I came across
a Heath meter with 2 scales, 0-10 and 0-50.  Looks like it could be from a
DX35 or some early transmitter like that.  It's a little over 2 inches
square with the classic black bakelite (?) case with three vertical ribs on
either side of the zeroset screw.  Can anyone help me identify this?
Thanks and 73,
Mike W2IY
