First things first: having found your possible source, we move to - Israel, 1948-50
It's almost as bad as French aircraft, and proof Wiki is, at best, a 'second source' (I wasn't using it).
They are all over the place with their "A" and "B"s. Of note: "Both Italy and Israel bought a single TE-1B Buckaroo in 1948.", but the Israeli AF calls it a TE-1A and notes that it was powered by a Continental C-145 although the only engine Wiki lists is the Franklin. Matters not - it's a TE-1 (A/B) but there might be a story.

Onward with this crazy little number...
