After so long, and work having started to bring the clock into repair, here is part of the email from the horologist explainating the reason for the further delay:
"Unfortunately I have been let down by my painters. The hands and mechanism covers were promised to be completed and with me by today latest however I have been chasing them and it seems that almost everyone has taken the rest of the week off.
This means that I won’t be able to get everything completed and be on site this Sunday. I am then unfortunately away in Greece on Sunday 30th but can allocate Sunday 14th as a revised date for installation.
I am really sorry about this and hope the revised date will be acceptable to you.
And yes , I have now included internal illumination".
More details about the clock are contained in earlier post.
