In my collecting adventures I have acquired a box load of B&M Visible Powder Measures. 7 of them.
Looks like the guy bought a new one every 5-10 years, or maybe he collected them.
Is there a web resource for collectors or users? I'm trying to figure out how old each of them is. The differences are tiny. Name plates w/wo the city or blank. Plain brass vs coated brass finish. Knurled lid edge vs smooth edge. Short tube vs long tube vs micrometer tube. They are otherwise identical. Looks like you can swap any parts across all the units.
B&M is still in business, claims to have parts but is pretty much non-responsive. Any leads or help will be appreciated.
