This mechanical VT clock, for a cyclo cross outside broadcast for Pebble Mill, pre-dates the electronic VT clock invented by Peter Wood-Fisher, which was added in post production. The clock would have been recorded as part of the OB, with the details of the take chalked in fresh each time. The clock would then have been used at the front of the edited insert in VT.
Thanks to Ian Collins for making the grab available.
