I am taking a stab in the dark that this is indeed the Rumford Model as I cannot find any adverts with this on. The crystal this takes seems to fit two models according to GS catalogues, the "Hadley" and the "Rumford". Indeed they look near identical but this model has different lugs (see Hadley watch also listed). If anyone has any better ideas as to the model please let me know and i'll update, for the time being it will be listed as the Rumford.
Case Serial No.
