Then of course there's Finland. There was great interest in the FAF for G.1 but eventually Douhetism won over and we bought Blenheims instead.
Double-bluff what-if: what if the Spanish Republican order that as a cover story was a Finnish order, that being plausible due to the interest, would have been actually dellvered to Finland eventually? Even in OTL this almost happened in the autumn of 1939 but the price was deemed too high. Then after Winter war started, it was too late so the offer was abandoned again.
During Winter War, squadrons of G.1's would have been a nasty surprise to unescorted SB-2 raids.
