Only two never received which could count for dxcc mixed: VO6F 2/15/47 40 CW and PK3TT 9/9/47 20 CW Don't suppose any clues left on these? Another one wouldn't count but would have been nice was MX2B in 1938 (that opr is a sk and the logs no longer exist). I do have an MX2B qsl on the wall from the estate of W6ALQ. 73 Bob W7LR ex W6PBV VQ3,4,5 MP4BAL HS1L
