Pot ID help please

At our recent club auction I came home with several pots.  These 2 have the same chop mark and I have not been able to identify the potter.  Your help is greatly appreciated.

Here is pot one:




Here is pot two:


And a tracing of the chop.

Anyone have any suggestions as to how I can identify this potter?

Have you looked here: http://www.gobbs.org/chops.htm

Dang, Jim. You're a wealth of information. I had no idea such a site existed! Pretty cool.

Thanks Jim and the answer is yes plus another 10 sites I have bookmarked. Maybe I should provide all of them in a single post. But still would like to identify this one. And I also have another. I call it my "PORK" pot. A backward P and what seems like the rest is ORK. Probably should just make it a separate post. But here is a peak. (PS Merry Christmas Jim -- and to all others.)
