1960s Parker Timer mechanical parking meter timer

A vintage parking meter timer from 1960s powered by the Swiss Baumgartner caliber. It can time up to 4 hours countdown. Just set the duration, wind up the crown and it will count down and buzz when indicator reaches 12 o'clock. The service history is unknown but is working fine and buzzes ok. Some aging marks/rust spots on the base metal case and clip. Quarter shown for size comparisons. Please email for any queries thanks.
