pittsburg crock gar ???
Answers:
You need to provide more information and phrase a clear question. I assume that you have some kind of antique crock made in Pittsburg, but what does "gar" mean. The only "gar" I am familiar with is a predatory fish. You might want to provide more information, clarify your question, and repost it.
Good luck with your search for information.
