Well, um, here's the other interesting part of this story: There are
no numbers on it anywhere.
Weird, huh? No numbers on the body. No numbers on the vacuum

on the advance mechanism, and found none there either.
So the truth is, I really don't know what I've got, other than a
brand-new 45D4 shipped from England...
