More info. Happy birthday to me 
Thats better. Shoes correct way round and another of my used shoe steady springs fitted now holding the shoe against the back plate with reasonable force.
Old spare pair of pliers modified with angle grinder to fit into shoe steady spring for fitting spring to backplate.
Shoe steady springs:-
Left to right 1. too squashed does not hold shoe in; 2. probably 0k; 3. new from MOSS but so difficult to fit due to hook end being too long; so 4. cut small piece off end of hook and was able to fit. I also marked 2 positions on the backplate where the hook wire had to line up to enable hook to be pushed in and be turned through 90 deg. Hook starts nearer axle centre so hooks outwards into backplate bracket.
The nice guys at ESM Morris Minors advised that their new springs were very difficult to fit - I suspect that was for same reason as the MOSS spring No.3 above with too long hook end. (that was why I got new from MOSS instead of ESM at a higher cost and higher postal......now wiser).
I noted that the MOSS Morris Minor parts catalogue shows the rear lower shoe the wrong way round (cylinder shown on left on backplate but shoe has cylinder notched end to the right!!.......if it was correct way round the double holes in the shoes would both be at the pivot end.......this could confuse and allow someone to put shoes on wrong with double holes at opposit ends.........that contributed to over streched and difficult to put on pivot end pull off spring and probably too much tension pulling shoe away from backplate.
With all new items the snail adjuster requires 11 clicks to get shoe to touch drum. I made a 3mm spacer to fit between shoe and cylinder but it was too thick so will wait till shoes bed in and wear before fitting. I have previously had the problem of running out of adjustment as shoes wear long before minimum lining thickness is reached.
I am now using the snail adjuster from the 8 inch Lockheed brakes. It is slightly higher to start with at zero adjustment. The notch on the end of the shoe has to be enlarged slightly to take the larger diameter snail spindle.
Using a digital calliper fitted between bottom of MASK and top of cam adjuster I took the readings for each click of the adjuster:-
ADJUSTER READING increment ADJUSTER READING increment ADJUSTER READING increment
0 13.5mm 0 8 14.60 = +0.17mm 14 17.30 = +0.60
1 13.7 = +0.2mm 9 14.82 = +0.22 15 17.91 = +0.61
2 13.92 = +0.22 10 15.15 = +0.33 16 18.58 = +0.67
3 14.08 = +0.16 11 15.65 = +0.50 17 19.21 = +0.63
4 14.18 = +0.10 12 16.16 = +0.51 18 19.99 = +0.63 MAX
5 14.28 = +0.10 13 16.70 = +0.54 Total adjustment = +6.49mm
6 14.37 = +0.09 14 17.30 = +0.60
7 14.43 = +0.06 15 17.91 = +0.61
Since pivot end slides then total adjustment over whole shoe is halved = 3.29mm and since lining is around 5mm then a spacer may have to be inserted tu use lining down to thinest permissible.
