Although date of manufacture for Browning Arms import “T” prefix series pistols from ’64 though ’68 may be found on the US Browning website (
www.browning.com/support/date-your-firearm/hi-power-pistol.html), FN actually produced the “T” series circa ’63 through ’72. The US Browning website “T” listings are specific only to the “T” prefix series pistols imported by Browning Arms. If a “T” series pistol is FN marked…or is outside the serial number range listed on the US Browning website you’ll have to treat it as a Post ‘45 “Classic” pistol…
see below.
For Post ’45 “Classic” pistols, Post-Occupation “A”, German Occupation and Pre-War pistols identification becomes just “a bit” more complicated and requires reference materials, a knowledge of period serial and contract numbers, a thorough understanding of all the markings…usually quite extensive, to be found on/in such pistols. And then there’s the Ouija board, mystical incantations, the cauldron and of course chicken bones.
