Glastonbury Duplex cancels and CDS

According to Parmenter, Glastonbury had a number of duplex cancels both 4VOD and 3VOD - I only have examples of the latter.  The town cancels on the first two are of different sizes (20mm and 21mm).

 The duplex cancels are known in use until 1910, which overlaps with the single-ring cancel seen below from 1908.

 And finally a double circle double-arc cancel from 1930 - "unfortunately it has rained hard all afternoon".
