Hello
You have a registry set titled Registered Sets in Belgium 1905-1997 Complete Set, P67-P152
My note is Pick 62d and is a 20 Franc denomination and is dated 30 October 1909 and is thus well within the set's date parameters. Alternatively, the Registry set could start at Pick 61. Pick 61 to 66 inclusive are still relatively available unlike issues up to Pick 60 which are practically non-existent on the marketplace.
Would welcome proper consideration of my request.
