Somerton - part 2

The next handstamp in use at Somerton was a single line "SOMERTON" handstamp, in use from 1790-1799.   This entire poses the difficult question of which side to display, as it also has a single line "ILCHESTER" handstamp in use from 1791-1799 (according to the BCC both are rarity "E").  I decided to put it under Somerton as Ilchester came under Somerton at that time.

Moving along, the next two handstamps are "SOMERTON / 135" handstamps, fistly with the mileage boxed and then with the box reduced to lines above and below.

 I cannot deciper the postal charge on this second entire - any ideas ?
