Is there a resource to look up the license number assignee on Phillips drivers? Or maybe someone knows offhand - specifically looking for license #28.

Not been able to dig up much and I thought I recalled seeing a thread somewhere here about it.

Any help is much appreciated.

Here is an old thread from g503.com on the subject. I'm not sure how much help it will be for you because I didn't see License 28 discussed.

Thank you very much. Will look there and see what I can find.

Interesting site.
