The tag is from a ballot box that was sent to the deputy returning office by registered post in June 1962.
The postage paid was $1.30. At that time the registration fee was 35 cents so the base postage was 95 cents. I want to find the parcel post rates and so work out how much the box weighed.
In 1965 the rate for 4 lbs was $0.78 plus 1 cent for each extra ounce
for 5 lbs it was $0.94 plus 1 cent for each extra ounce.
If these rates applied in 1962 the box would have weighted 5lbs 1oz.
Can someone please confirm the 1962 rates or point me to an online source.
