If I recall correctly, I believe the model in your photo, Bac, is the original design that Taurus more or less clones to this day, isn't it?
Sort of. The Taurus PT92 still has the safety on the frame like the original 92, but the trigger guard is squared off and the mag release is behind the trigger guard. The old Berettas had the mag release on the heel of the grip, in European fashion.
Furthermore, the original, very first Beretta 92 design that went into production is actually pictured below. It differs from my 1978 model in that it has an extra "step" mid way down the slide. Beretta manufactured a little over 50,000 of the standard 92, but only the first 5000 of those had the original slide. Also, since we're going back 40 years, many of those 5000 probably aren't around any longer, so finding them is not easy these days.
The original 92 grips were just these drab checkered plastic grips with no logo. Later, the smooth wood grips on my 1978 model came about.
