Jeff’s answer was spot on, that’s likely why nobody else replied.

Normally there is no real value to a bagatelle, but this one is kind of neat, being a Jennings and having some interesting features.

The Howard products are a god send for this era of games. I strip the playfield and put all the metal into the heated ultrasonic then polish in walnut media with Flitz in a brass tumbler. I coat the playfield in Howard Feed N Wax, let it absorb and re-coat, repeat until the playfield stops absorbing any, then wax with Blitz. For the cabinet, I use Howard Restore A Finish, then follow with Feed N Wax until it stops absorbing and wipe off excess. Once all the metal has gone through the tumbler, I hand polish with Flitz, then coat with Renaissance Micro Crystalline Wax And Polish, then do the reassembly.

I remove the pins and they go through the ultrasonic and tumbler, too. I find something I can use as a guide (socket, a bit of metal tube, etc..) to get the pins all reinstalled at the same height and put them back in just a bit lower than they were before.

For replacement pins, I take samples with me and check a local hardware store that stocks a good selection of furniture fasteners in addition to normal nails. I try to use the replacement pins in less conspicuous areas.

I prefer Purple Power, but sometimes use Simple Green if I’m out of Purple Power. I have a cylindrical plastic container that I fill with the parts and cleaning solution, then drop that into the ultrasonic (I run it at 60c… the heat makes a huge difference). For little parts, I use a small jar with the cleaner, saves on cleaner and cleanup.
