Main period sans-serif 25mm UDCs under Glastonbury, Wells and Weston-super-Mare

There were five offices under Glastonbury that were issued with UDCs.  One, Street, was issued with two.

Street had UDCs issued on 8th January 1848 and on 26th June 1849.  The example below in grey-blue from August 1857 is probably of the second UDC issued, which is known used in blue from September 1849 to December 1856, and in black from April 1854 to November 1859.

Wells had  18 offices that were issued UDCs, one of them, Cheddar, was issued with three.

Cheddar was also issued with multiple UDCs, on 7th December 1847, 17th March 1851 and 24th April 1851.  The last UDC was issued immediately after the previous one and one might assume that it represented a problem with the previous handstamp.  The example below, from 10th December 1858, appears to come from the middle UDC, the one proofed on 17th March 1851 - see the write-up for images of the strikes in the Steel Impression Book and why I think it comes from the 2nd UDC.  Let me know if you think differently !

Weston-super-Mare had nine offices that were issued UDCs, three of them were issued with two.

South-Brent was issued with UDCs on 15th June 1852 and on 17th March 1857.  The first of these is known used from November 1854 to January 1855.  The example below is from November 1854.
