    Hi Adam, To answer your question if it was possible to call a number on an old dial phone line by rapidly pressing the “crossbar” (instead of using the dial), the answer is yes. I used to do it myself back in the day. The phone line only has two wires, and the old switching relays at the main office were just in series with the phone line. The dial just interrupted the line (the same as pressing the crossbar) to advance the relays one position at a time. For example, dialing a 7 or pressing the crossbar rapidly 7 times would advance a relay 7 positions.
    Besides Blackie surviving being shot with no ill effects (as you mentioned) , the plot has several other gaping holes:
    • Why would any criminal in their right mind install a phone (even though it had no dial) in a prisoner’s room, since phones back then were always getting sales calls and wrong numbers (just as now) to which Dollly could have pleaded for help.
    • Why would Dolly have called Blackie in the first place. She might possibly have called the police hoping to create a distraction for her to gain entrance to the safe in the cellar, but why alert Blackie, since he would discover her true plans pretty quickly.

    Love your show.
