ID cards, for those familiar with them, on the side of their photos are dates ranging from 1918 to 1923, there are also some numbers which I do not understand, example on this link

Hello John and welcome,

The cards are CR10 not GR10. The dates shown by the right of the ship's official number are the dates of engagement on the ship, dates of discharge are not shown. The number on the photo is the seaman's ID card number or RS2.

Regards
Hugh
