How about you read this the other way round, with lots of phonetic spelling:
He started writing:
Overlooker in a woollen mill.
Then decided to add something else...
Chelsea...
(but then ran out of room, no space below, so squeezed continuation in the space above but still in the right box)....
....pensioner and sergeant major in the Halifax Foot Guards?/Company?
Edited: line at the top is different because it was written to fit in to smaller space, so looks like a different hand
