Piethe und Didczuhn - Rastenburg




August Lneburg - Kiel

I'm going to make a stab that the above are on Jger/Bittiner DRP 176578 of 1904 and don't have the advancements of the 1910 design with removable right screw on hingepin under DRP 229521.




J. Novotny retailed Bittiner design under DRP 201505. So indeed the Rekord design under DRP differs in some manner from the original and I would assume the slight difference allowed Carl Bittiner, and possibly Edmund Bittiner to market the model. It may be as stated that it has 20 friction points while the original had less.

Kind Regards,
