You will have to contact Browning on this.They have a serial number search option in the customer service site.My records indicate that the Browning hi-power had a letter T prefix from 1964-1969.In 1969 they switched to the prefix of 69C and continued until 1976 with the prefix of 76C.
Browning's web site has a sn search function.
The prefix numbers and letter 72C indicate that your Browning High power semi auto pistol was made in the year 1972.

Browning did not break down the serial numbers of the hi-power from 1945-1954.At the end of 1954 they had made 72,250 guns and then started to register there serial numbers with production in 1955.Your browning high-power falls into the production of guns from 1945-1954,I am sorry but that is the best that I can do.
Your browning hi-power was made by FN of belguim for browning in 1969.
