As it read in the pages of SN, Brodak bought the kitting rights from GMA (and Bob Palmer). In those cases, all the designs had been bastardized enough to make an authentic version (plans signed off as being authentic by the original designer) legal in a court of law. TF's loss, and Veco has been out of bidness for what...35 years?
OBTW, you might note that our man Patrick has plans available direct for designs that are kitted by Brodak, RSM, or others. This is perfectly legal, because the drawings are rearranged, and typically have much more detail, such as patterns for all parts, that may not be shown on the kit version. He has the Cobra plans. You might ask him if you can buy a copy of the plans and a copy of the CAD file, to have a kit laser cut for your personal consumption. Ask Randy or Paul about the control ratios, tho.
