I wanted to post some follow-up information since some of you were interested in these old grinders.
Definitely invest in a reproduction catch cup if your grinder comes without one. They are worth every penny. It is really hard to hold a paper filter under the grinder, turn the handle and not whack your knuckles! The catch cup makes it very easy to use. These are readily available online or with the glass canister type, you could probably find a nice little glass at a thrift store that would do the trick too.
A little reading on the canister grinders shows that like mine, they do require a little manual assistance, because several times during the grinding, one bean will block the flow of the others. This is easily helped with a jiggle or a tap, but that doesn't work with the wooden type like mine since it is fixed to the wall. I have a metal shishkabob skewer that works great. I just put it in the canister when I'm grinding and give the beans a little swirl when they get stuck. These take a little more effort than a modern grinder, but I am really enjoying mine and love how it looks in the kitchen.
I got the following info on cleaning the interior of a grinder from a person who has a business online restoring and selling old coffee grinders:
"Take the metal grinder off (two screws on the sides) and wire brush the interior."
On the wooden box:
"The nails will pry out with a small flat tipped screwdriver so you can remove the glass and lightly sand the interior with a fine sandpaper."
Since mine had been in constant use, I decided against it, since there were no signs on the grinder of it ever having been opened and I didn't want to mar the old screw slots or the metal lip of the box. It was in such solid, tight condition, it seemed best left alone.
