Actually, there are 2 covers on the 222 that can be removed. If you remove the bed, you'll see a screw on the bottom of the "tunnel". There are a couple more oil spots in there. ETA: The rest you access from the top, by removing the throat plate.

It's extremely rare to be able to grease with no excess grease getting anywhere. Usually a little squishes from between the gears and balls up a little around the gear. (and flings off elsewhere if it's excessive). If the gears seemed dry to you, they likely were. They should literally look a little moist in the areas that mesh together.
If you can, see if you can get Glenn to show you how to maintain the 222. These little machines were meant to be maintained by the owner. For the most part, de-linting, oiling / greasing you can do on your own. Other issues, should be looked at by someone with experience (which doesn't always mean an OSMG)
I've heard the 221 sound described as a waterfall. This one I find is similar, but seems burlier,... like a bigger waterfall?
The 301 usually use has been complaining a little on the last 2 projects I did. She's been oiled and cleaned, so I think it's time to look deeper at the motor. No big deal, I just need to get her out of her table and put her on the bench. The other 2 301s here sound great. They're smooth and quiet. Not as quiet as the 201, but much quieter than the 503 and the 15. The 411Gs may be comparable.
Glenn also deals with us Canadians. When you talk to him, tell him Tammi said Hi? I got some stuff from him at the beginning of the year for my 222, and he was very helpful.
I would definitely like to hear the story.
I thought it odd the way he'd not respond to my emails for a week at a time, but in the end, everything arrived as expected, and he knew his stuff. Forgetfulness would explain a lot.
The only gotcha I got him on was the case. It looks like we Canadians -did- get a different case than the US or British machines. (US locks, and the FW barely fits in it. The rear hinges look a little different too, as do the clasps.) I've come across another one since. A friend found one and had me service it. Same exact case.
I'm glad you're enjoying the site. I don't get as much time to post as I'd like to, but I try to keep it entertaining and educational at the same time.
