Another clock repair enigma

I'm only a tinkerer with clocks, but learning a bit, and this movement has me totally stuck (not difficult!).

OK, here are the details.

Clock runs and keeps reasonable time, but it chimes at ten past the hour (1/4, 1/2 and 3/4 all at the same point, one after the other). I think it chimes (and certainly strikes) on the hour as it should.

If I advance the minute hand it chimes at the correct points every time, but not when under clock power!

Any ideas, please.

However it is not locking when going into warning then the chime correction mech is putting it back into sync on the hour, at 10 past the warning wheel should turn about half a turn then lock until the minute hand reaches quarter past when it the lever drops of the centre arbor cam. best to pull the movement out and watch it

Thanks for the quick reply, Stephen. These chime and strike movements are rather intimidating to me. I will try to identify this chime warning wheel and go from there.

I'm guessing this chime warning wheel needs to turn at 25 past and 20 to the hour as well? I think it chimes on the half and three quarters, if the clock is started after the quarter hour.

First of all I need to make a decent stand for holding the movement while out of the case. I will get on with that once I have changed over my lathes, which is progressing painfully slowly at the moment.
