sessions westminster pendulum length

[mrxmttr 1]

I am working on a Sessions Westminster that I believe is a 416 W.C. or a Westminster chime C.  The clock was missing the pendulum and weight so I am wondering if anyone could help with pendulum length. Any input would be greatly appreciated.

This is a two train Westminster chime ? the pendulum rod will hang to the very bottom of the movement plates which places the pendulum bob just below the movement , the suspension spring and rod would be 5 1/8 inches.

Photos would help.

Hi   I second that Old Hippy.  Well done wls1971, as an avid trawler of the net and member of a few forums there is always some on who can find data and help

I have two, two train Westminster clocks one German which I believe to be made by Peerless (Mathias Bauerle) for which I was able to find with help on another forum the original patent information  and a English Gillett and Johnstone, both these clocks use remarkably similar differential gears for controlling chime and strike on the hour, whilst doing research on those I found the Sessions clock information , I do not envy mrxmttr his work on this clock, all information states they are a absolute nightmare to work on

Thanks you all for the help. And yes this clock is a little more difficult than many others but it is reassembled and running. just not keeping accurate time yet. I hope to make that happen with the help provided by this forum. Thanks again.
