Hi,

BA-15 was a 5/6 seat light transport airplane Project,powered by one Lycoming IO-720 engine,
later called MFI-22.

MFI-23 was a float version of Ba.14

Also a drawing to Ba.12

Very nice, hesham, Andreasson is an underappreciated designer. He was also an engineer in the San Diego area (Convair?) for a quite a few years and active in homebuilding, the original BA-7 he built himself was different from the later productions versions. It's all-moving tail surfaces may have influenced another homebuilt aircraft designer working at Convair, Bud Evans of Volksplane fame. Here is a pic, note the upright all-moving vertical tail unlike the swept two-piece production version:

And one of the BA-12 ultralight:
