Here are a few pics of my Browning HiPower T-series (made in 1968, purchased in 1969 by my father).
It is all original (even with mag safety disconnect).
The pistol has one of the BEST triggers of all my pistols (even comparing to my much newer HiPower without mag disconnect safety) . I don't know what the difference is but a great trigger is definitely possible with a HiPower.
It's a shooter, not a safe queen. At the range:
