    I have just bought from an eBay auction a radio which seems to be a R 3 from De Forest - Crosley. There was not  case, only the chassis. It is in fair condition, all components inside, transformers OK... I have drawn the schematic, is a reflex with regeneration like Trirdyne, or 3R3 from Crosley. The sockets are mounted on a hard rubber board which is marked  "R 3  1906"  .  Last number seems to be a year but it could not, at 1906 there are not this kind of receivers.. I am enclosing some photos.
