Yes Ron, it is a struggle and it makes me wonder if some tools were still losse in the toolbox and not in the toolroll.
Feeler gauges and magneto spanner will fit in the pocket on the right. The fourth tool from the right (spanner) was not part of a BSA WD toolkit.
I have now measured 3 different original toolrolls, because I was wondering if there are maybe larger ones. They all had approx the same dimensions, difference was 1" maximum.
It's the same with the Norton kit in the leather roll, and in fact the factory illustration doesn't show them all within loops and if they are, it's a devil of a job to roll.
