CD 145 [010] B.G.M. Co. I've collected BGMs for a number of years. The price guide led me to believe that the CD 164 was going to be the most difficult one in the series to get but experience has shown me it was the 145. I've seen a few over the years but they all had considerable damage. This one has a single shallow base flake measuring about 4-5 millimeters which is less than 1/4 of an inch. There is a little bit of a faint dome scuff as well. Given how hard these are to find, I doubt it is upgradable since it seems the 145s and 162s are prone to base flakes due to the apparent delicate nature of the glass or manufacturing process. I haven't seen one offered in the PicturePoster for quite some time. The last posting of one that I could find was back in 2008. If you are looking to upgrade or looking to finally acquire one, this is your chance. Price $500 plus shipping. First email as always.
