R 24 Motornummer

[boscho]

Hallo und guten Abend,
ich habe in meinem Teilefundus ein R24 Motorgehäuse ohne Motornummer gefunden. Das Gehäuse hat noch die Originale Sandgußoberfläche und wurde nicht bearbeitet. Wurde hier vergessen die Nummer einzuschlagen oder handelt es sich um ein Ersatzgehäuse?
Viele Grüße
Georg

I asked BMW Classic Archive this question a long time ago. Answer was that 'replacement 'crankcases' were available, and supplied unmarked. This is OK,  but if perhaps the engine was something special, say an R68 / R5, a 'replica or false' number may by be stamped, by a 'Crook' Thus making the vehicle suitable to sell.

BMW in their wisdom have over the years collected photos of 'known to be' original / correct stampings. If I recall I was able to confirm some VIN  numbers on pre war BMW's sold in Britain.
Because I am the Registrar for BMW's sold by AFN Ltd 1935 -39. These records ( 220 ) are very comprehensive, even some time listing a telephone number in 1938 !

I do not think Frau Windbeutel would have had a telephone then !! Only the very well to do (rich). I grew up with telephones in the house. 1940's !!!!. Not ours, my Father employer. He was a Gentleman's Gentleman. a Butler.
