Postal Rates
Click on the link to see the rates for the country/dependency/colony
Note: The listed rates are not necessarily complete - this what I have identified to date.

All errors are mine alone. Additional information and any corrections are welcomed

Listed postal rates for each Country, Dependence  or Colony are described for
     - Local rates
     - Empire rates
     - Foreign rates
     - Airmail rates (if applicable)
     - Parcel rates
     - Other rates
Note: In some instances rates are quoted as to June 1935 and from July 1935. These are rates where UPU documents quote a changed rate from the rate quoted six months previously. I have not been able to confirm exactly when the change came into effect and have abitrarily used the June and July dates. In other instances the months of change known and these are quoted.
