Here's a Dayton 166 counter scale... They're on eBay all the time...
I'm looking for the scale sitting in a Mom & Pop Shop for $100.
That looks like a old timer... I'm not famliar with scales I just saw
this Dayton style and am now on the hunt for one.
And yes seems NK was mainly up North East though it was big in Washington
and I've seen several little 7oz bottles from Little Rock....
We had one of those Dayton scales at my dad's drugstore. Should have kept it because the guy who bought the store probably just threw it in the garbage!
