Shepton Mallet 'Dulwich' Cancels

A 'Dulwich' cancel is a double circle double-arc cancel, so called because the first one was issued to Dulwich.

Shepton Mallet has had a number of 'Dulwich' cancels, the earliest type of which were of the form "SHEPTON-MALLET / +" with a maltese cross at the bottom.  Some of these are illustrated on this first sheet - with examples with thin arcs from 1903, slightly thicker arcs from 1905 and thick arcs from 1930.  There are probably more varieties used in the intervening years.

This next sheet has a "SHEPTON MALLET SOMERSET / 1" cancel from 1939. 

The cancel is slightly unusual as the date inside is not aligned wit the lettering outside.
