Hi perf12,
I've seen this list before but I think it's confusing and it looks incomplete to me.
The only three post offices in this list that had dated postmarks were
Hanya (Chania) , Kandiye (Heraklion) and Resmo (Rethymno).
All the others are undated postmarks.
Ayi Nicola is a strange one. It's in Coles & Walker's list but there is no illustration and it's not mentioned in either the Feenstra or Galinos handbooks.
The only postmarks I've seen from there are the French post office CDS "SAN NICOLO" and the CDS from the autonomous Crete post office from 1900 onwards.
Esfakiye Sultaniye is also a problem.
I think this is repeating an error in Coles & Walker and should instead be "Esfakiye Sultaniye (Vamos)".
The village of Vamos was picked by the Ottomans as the local government centre for the Sfakia district and became known as "Sultaniye".
Hora Sfakion / Sfakia is a separate village further south on the coast.
I would follow Feenstra & Galinos who both assign this to Vamos.
The list seems to be missing at least three offices in Kastelli Kariyesi, Kastelli Kyssamo and Mires (all had negative seal style postmarks).
Around another 13 post offices are believed to have existed according to an Ottoman government publication but as far as I know postmarks haven't yet been identified for any of them.
I'd be very interested in other opinions on any of these points.
