Thanks for the comments on the wall. It's not been the most productive week but now 1000 bricks in after 10 days of work. I'm not sure I will get the productivity much above 120 a day with the general work involved in preparing bricks. I appreciate the description as 'steady'!
A I being too selective with the bricks? Maybe... The ones on the back are certainly not as good. The piers aren't as uniform as I would like given the variations in the bricks but compared to what was there before it is a big improvement. Hopefully I won't run out of decent bricks.
Covering the barrow up has certain helped. It has been warm over the past few weeks.
I'm not sure I'll be adding a falling soldier detail mind you.
