Heather, hope this all makes sense. I’ve inferred several things from the info below. Finlay, I suspect is the circuit judge and could c.m.h.l be six calendar months hard labour.
The info I have from Prison records is as follows;
John Richard Braithwaite, 22 Labourer, from Barrow in Furness. Heard before Finlay, S.C. on 28th October 1921.He entered a guilty plea and received 6 months c.m.h.l
Thanks for your offer of help.
