Hi - this is my first post, and I hope I have the correct bit of the forum! I've just bought a lovely (and rather large!) Gustav Becker oak mantle clock (Serial no. 2152457, Freiburg 1925) from a local auction house. It keeps excellent time, beats perfectly, and the hour chimes are fine. There's a problem with the quarter hour Westminster chimes, however, which are not in the correct sequence (at the moment chiming two sets on the first quarter, with the sequence following round to chime only one set on the hour). What's more concerning is that the quarter hour sequence has shifted since I've had the clock (2 days so far!). This may be due to moving the clock? Is there an easy way of re-setting the quarter hour chime sequence? Grateful for any advice, please! Many thanks.
