An unrecorded inscription by Eric Gill?

To judge by its lettering, this tablet, in the church of St Peter and St Paul at Northleach, Gloucestershire, must be the work of Eric Gill. Not a brilliant photograph, made with flash and (one may as well admit it) with its verticals adjusted in Photoshop. But since this example is not in the list of Gill’s inscriptional work compiled by his brother Evan, nor among the additions made to it by David Peace, it seems worth putting on record.
