Royalistflyer I've got a few publications on RAF insignia and haven't been able to find the badge you describe worn as a sleeve badge. What you describe is the badge worn on the officers' field service cap (sidecap) but in gilt, not bronze, so I am at a loss. In any case I think we have established that there was never such a rank as "commissioned warrant officer" in the RAF (as opposed to warrant officers who had been commissioned, of whom there were lots!)
Bill, you are quite correct. I held a supplementary list as opposed to a general list commission - I think thats what MPN 11 is alluding to, but as far as I was concerned it was still a "full" queen's commission.
