Peter,The film compartments of the post war Gray Baby 4x4s were too small to accept a 35mm cassette.
Too bad that the oddity camera site did not have a picture of your "Super Zeiss 9x12" with f1.5 Sonnar.

Actually, I have most/all the bits and pieces for a 4X4 - to 35mm conversion for the Baby Rollei. There most certainly was a Rolleikin for the 4X4, but I don't know if this was a Rollei item or made by a third party. I haven't bothered to get it out and fit it to one of the Babies. P.
