[TheForge] Interesting air hammer pic

I agree Steve, it sure looks like a Massey.

Might be somebody else's though. The Massey patent # us707,246 is for the
control valve scheme rather than the hammer itself. The hammer example he
used in the patent drawings looks pretty much just like this one though on a
smaller scale.
