Brad, I have a Rega-specific Wallytractor I no longer need (sold my RB300). I believe Wally has health issues, and is no longer producing his products. It was quite an ordeal getting my protractor from him after sending him the $. I had to get Fremer involved, which is what finally did the trick.
The protractor is in storage in S. California, but I'll be bringing it to my new place up here in the Northwest next month. If you're interested in it, you can contact me via a pm if you wish---Eric.
