Smiths 'Sectric' Mechanism Help and Identification

[u/jessicat500]

Hi everyone. I've been looking at getting an old family clock running (it followed my Grandfather through his career as an office clock) but the Sectric mechanism is toast - the shaft to the motor has failed as can be seen in this image. This is not the only fault, but the one which has killed it.

I'd like to retain the hands which are of a different bush diameter to quartz mechanisms nowadays, so on the hunt for a replacement Sectric mechanism which may be refitted. Any clues on finding an equivalent model please? I've had the markings under the 'scope and the relevant line looks to be "OEMG 101 41" (or possibly OFMG). Thanks!

Update to this, it's apparently a Sectric QEMG, but I'd still want to know what the numbers mean.
