I had to hang up my flying suit in 1999 following a final failed medical. In the pocket are two Chinagraph pencils so probably modern at that time one blue and one red. Made by Staedtler and embossed with "omnichrom and 108-2 for the red and omnichrome 108-3 for the blue both wooden. If any use PM me.
