From The VAOS Section J1 Camp Equipment 1941 edition
stores No JA2393 Valise, Officers
Canvas for officers kit, see List of Changes ref A1878 (which will be the introduction one, about 1925 comparing it to a list of Lewis gun LoCs I compiled) and B1075. It should come with a pair of leather straps and a connecting band that acts a a suit case handle. cost £1 9S 6D back then if you had to replace it.
Very nice!
If any one wants copies of the VAOS books I've scanned in let us know. theres about 30 of them,
I'll get my anorak and flask of warm lemon drink...
