Note small"4" in "24TH"
The hand stamp was said to be in use for a month but in Robson Lowe' book mentioned one week. The majority of existing covers were dated 24 December 1946 and were invariably philatelic. Other dates are hard to find. The chop was valid for use on the BMA stamps of both North Borneo and Sarawak. But examples on Sarawak stamps are fairly uncommon and well worth looking out for. The use of this hand stamp on Australian stamps and covers are a bit of a mystery as stamps from Australia were only allowed to be used immediately post war before the availability of BMA overprinted stamps. They were philatelically inspired and there must have had been some laxity in the post office services in those chaotic times.
