Barry,
I have a shell just like yours; I am in Arizona. If you could email me directly at karl@northlink.com I can send you some pictures of mine. The only thing I am worried about is it seems like some of the imperfections on yours are the same as mine. Hope they are not made from a mold??? Will try to take some scapping from the back and see if the material melts?
Look forward to hearing from you,
Karl
