As you may have gather from the previous posts, I'm catching up with some recent acquisitions in alphabetical order ... and I've got to Hatch Beauchamp. The Letter Card below has "HATCH BEAUCHAMP / TAUNTON.SOMERSET" double circle double-blob cancels (not sure what the approved terminology is for these cancels) and is posted on the first day of issue of the 1½d KGVI stamp.
This next item from Henstridge also looks philatelic, being an Air Letter posted within Henstridge in September 1957.
I don't understand the postal markings on this next item from Holford to London - it has a "HOLFORD / BRIDGWATER . SOMERSET" double circle double line arc cancel dated September 1958 (aka a 'Birmingham' cancel after the first place to be issued with them) and it has a "MINEHEAD / SOMERSET" unified machine cancel dated June 1959. I don't understand the two postmarks with just the one stamp.
And finally a Valentine envelope posted from Huish-Champflower to Corfe with a faint partial "HUISH-CHAMPFLOWER" udc as well as transit marks from Wiveliscombe, Wellington and Taunton, all dated February 1857.
