2 deep sixes 6R .1 has an 03 designated ink stamp and the other is either 1/67 date code or 11/67 date code .I think it is 1/67 which could be the earliest deep 6. With either of those date codes it could only be an 03.
2 deep sevens 7R. 05 stamps
All restored.
I took pix of stampings and dates
$20,000 or best offer
