I suspect there is a fair chance that the M.O.S. (Ministry of Supply) entries for late May 1940 are the assorted machines grouped together under contract C7372 which were booked in at Chilwell on 1st June 1940. Some of the MoS entries have replaced a crossed-through "Stokvis" allocation. Stokvis was the Dutch importer and of course no deliveries had been possible there since 10th May.
C7372 was a "sister" contract to the mixed BSA contract C7370 and the Norton contract C7371 (which was for 16H, but "delivery already effected to Stirling").
Interestingly, most of the M.O.S. bikes are listed as "UP" which indicates "Upswept Exhaust".
There were spare engines and gearboxes supplied with the contract, but no mention of spare frames. It's quite likley though that some were ordered under separate demands.
This one made it to Stokvis before the German invasion in May 1940 (but was then captured by the Germans):
And this one was diverted to contract C/7372:
