A mod came out in the mid 90s for chinagraphs that had us drilling a hole in the winder end, inserting a key ring and then attaching white elastic to the ring. Elastic also stiched on to one end of the flying suit pocket so that Bloggs couldn’t loose their pencil. This only worked if Bloggs could get more than one chinagraph.. supplies dried up in mid 2000s. Oldmansquipper, the Harrier pro boots were great thanks 😜.
