Teardrops n Tiny Travel Trailers

I went to a local antique/junk shop to look for a 7" cast iron frying pan for my racing camping trip, last weekend. The piece I picked up, for five bucks, was a 7 inch pan of normal depth and on the bottom had an empossed B on the top side of the back of the pan and an empossed H inside of an inscribed diamond on the bottom. The pan does have a fire ring.

I would appreciate any and all infromation I could get on this pan. I already know that it seasoned up well and provided great eggs, beacon and potatos this past weekend.

There are some people here that REALLY know their CI, but it may be helpful if you could post a pic (plus this forum is always more fun with more pictures!)
