I checked the E-Disk to look up the ones coppercoins didn't have images of yet, the four was a non match. The 1960-D RPM-021 was closest, but not a match. I feel this one is a D/D/D because I see two notches on the serifs. Keep it safe for now. Maybe someday it might get listed. (Wexler files when they become available would be the next solution)
