SB, thanks for the photos! Here are the results: Clock Type: Vienna Regulator Style, Altdeutsche type case Movement: Weight driven Time/Strike Hour & Half-hour Seconds Bit: Seconds indicator on dial, actual time per revolution of the hand is 45 seconds Pendulum Action: Beat adjustment by horizontal screw at bottom end of crutch to move crutch pin Gong strike: Coil gong mounted on movement bracket attached to back board. Made at: Gustav Becker factory, Freiburg, Silesia, Germany Year Made: Mid-1903 Please confirm that (a) the pendulum is suspended from the top of the movement mounting bracket which is screwed to the back board, and (b) that the beat adjustment uses a typical horizontal screw to move the crutch pin. I guessed this based on what I can see of the crutch. Many GB clocks made at this time used a separate pendulum leader fitted with a moveable lever that adjusted the beat, with the pendulum hanging from the leader. Very nice clock!
