Going the route "back to the future", I dug out my
old 1969 Gibbons simplified, and yes, starts at NC1
which thus coincides with 1990 Gibbons as NC283,
so Gibbons must have had a major re-number under
D: North China

I accept that simplified is just the boy scouts catalogue,
but will have to do until I find a specialised at auction.

Just as a FYI , there was a gap between NC59 and NC 67
so my Mao stamp was not in either catalogue, probably as it had
little , if any usage.
Cheers.


Can't explain the curious numbering in your old Gibbons. My 4th
edition of 1989 starts at NC1 and runs to NC385.

Sorry, but I can't help with Hong Kong either. Chinese, amongst other
languages, is just my day job.
