Instructional Cachet and Taunton Census mark

This Invoice, sent at Printed Matter rate in October 1948, was insufficently addressed to "Volis, Nr. Taunton" - "Volis" being the farm name - and received a framed cachet specifying the correct postal address (Kingston St Mary).  It then received a diamond census mark, probably applied at Taunton.

Here is an image of the Invoice that was sent.
