A couple of items featuring Wellington, firstly an entire with a partial two-line "WELLING / TON.S" handstamp from 1785. The postage to Bardon near Minehead was 3d for two stages.
Below is a postcard from Rockwell Green with a "ROCKWELL GREEN" steel handstamp and a "WELLINGTON / SOM / 860" 3-bar vertical oval duplex (3VOD) cancel dated 27th March 1905. Rockwell Green had become a Money Order - Savings Bank branch in November 1893 and would have received its steel handstamp as a result. Curiously neither the Rockwell Green nor the Wellington 3VOD cancel are in the proof books.
