I am the happy owner of a Seth Thomas street clock works after its collision w/ a truck. Number 2442, model # ¿ 5 ?. The factory hand written record does not appear to match what I have. I have repaired the damage and mounted the works in a ‘grandfather case’ ; it operates with a 10# line pull and a 6 lb pendulum. My questions: 1. What were the original line pulls and pendulum weights; pictures seem to suggest line pulls of 20-30 lbs and pendulums of 20 lbs. Why? 2. Any source of information on the switch mechanism to operate the electric dial lights? 3. Is there a source of replacement suspension springs or does one make a replacement (nothing listed on Time Savers seems to match ).
