Yeovil

The Yeovil boxed mileage handstamp was altered so that the mileage just had lines above and below (and the line below was weak).  Here's an example from 1823 with contents relating to claiming an army pension.

The mileage mark was followed by a dated double-arc handstamp - the example below from 1838 was charged 8d for 50-80 miles.  One has to stretch the post route to Salisbury to get the charged rate - any ideas on a better route for this item ?
