There seems to be an inconsistency here.

Models 52B1U, 52B2U and 52B3U have originally been created from Rider's and/or Beitman, and subsequently amended with images from Motorola folders.

On these folders, the models are called 52B. This is in accordance with a more detailed folder from 1952 that I have available, detailing the following sub-models for 52B.

52B5 - Black
52B6 - Dove Grey
52B7 - Grass Green
52B8 - Flame
52B9 - Hot Chocolate
52B10 - Middy Blue
52B11 - Clover Pink
52B12 - Azure Blue

These models have to be created and the collective material (except schematics) be moved or duplicated to those new models. No chassis information for these models was retrievable, but a number of them could be found on ebay, with their according model type stickers.

Models 52BxU do exist; according to antiqueradioschematic there is also a 52B4U, along with B5 thru 12, all from the original Motoral service documentation.

Who can take care of this? I will provide a digital copy of the folder 1952 (probably including more models that need correcting).

Thanks and kind regards
Mark
