The Beretta 950 B was first introduced in the early 1950s, with production continuing into the late 1970s. To determine the specific year your Beretta 950 B was made, you would need to check the serial number, which can help identify the production year. The Beretta website or collector resources can provide more precise information based on that serial number.

I don't have a specific year for a Beretta 950, as the model was produced over several decades, starting in the early 1950s.

Each production year may have distinct features or characteristics that can help identify it.
