Brent,
Metal is finished to an honest 320. Oiled with WD40 and rubbed with 4/0 steel wool. Latter mostly removes directional striations and changes bright finish to satin. A finish finer than above seems to muddy the case hardening.

Rob,
I was surprised also at 2012. That was about when the customer and I first talked about the project. I think Roger is about a year behind on major jobs but best to check with him.
