In his search for them he bought out the NOS of a shop in NC. They are Knowler (sp) and the machine shop said they looked older than me, whatever that means. Acutully I think I have a couple of years on them.
Anyhow, the box say's they are tin coated, anyone know why they did this?

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

I hope they came with rings... | | |
