Have Clock Problems? Ask a Clock Expert and Get Answers ASAP
Regardless of what the label says, most clockmakers used one of several weight manufacturers The information you need to determine what weights you will need will be on the back of the movement. Here is a link to a company I've used before for my tall case clock. http://www.clockworks.com/clock-parts/clock-weights.html
If you send them an email with details, they will tell you exactly what you need to buy to repair your clock. If you aren't comfortable with doing this yourself, you would need to find a clock repair shop locally to replace the weights.
Please let me know if you have questions.
