here is a well used original motometer
it is much easier to photograph this than the NOS ones
notice the detail of the wreath and screw heads
the reproductions are much blurrier the screw heads just have some marking on them ,
whereas the originals have a little flower or 4 lobed figure thats distinct
the leaves in the wreath are much clearer as are the berries
the face plate has crisper letters on the back for "summer" and "average"
as far as reproduction parts,its not a bad copy for the 30-31s ,
of course they dont make a good 28-29 reproductions at all
