Thanks so much for replying to my question! I'm pretty new at this so, please forgive my lack of info. =) From what I can tell, I believe they're shell, but I could easily be wrong. I took a picture of what I have l left, but unfortunately this page keeps telling me my picture is too big. Is there any way I could send it in a direct message on this site? Or perhaps another place here that lets you post bigger pictures?
