Hey everyone, I just recently had a DM7 come into my possession. I haven't come across much info on this marker other than it may or may not be one of the Billy Wing DM7s. I looked the marker over good and took it apart last night for a quick clean and it's in very good shape other than a cracked eye pipe. I did not see a serial number on it anywhere which I thought was strange, but I may have just overlooked it.
Can anybody help me out with identifying this DM7?
