This CD 162 H.G. CO looks to be EIN [080]. This is one of the transition-converted embossed types. See the August 1998 Crown Jewels article on HG CO signals by Gary Kline. I've shown it next to a near clear modern Kerr clunker to show that the H.G. CO does have a blue tint. I picked up the CD 162 back at the NIA National Show in Bloomington, MN in 2000. The lettering was painted white by its previous owner.
