This is the last of the CD 154s from different manufacturers that I found to photograph. This one is embossed: GAYNER // MADE IN NO. 44 U.S.A. / 12 This would be EIN [020]. Nothing great, just one from a different manufacturer. I can't find my Maydwell 42, which I have around here, somewhere! I do not own a Diamond marked one, but don't recall who manufactured them anyway.
