Not really a revist, I work over there and was out walking and saw the BM and was just wondering how to determine which one it is, because I did not see a listing. Thanks for info, that helps, a little clearer now. I will go back and take a photo and post, maybe even try to clean a bit to see if I can make it readable. Again thank you. I often work with the people from physical plant, sometimes information is not acurate.
