It is possible that some
50bhp machine were also produced - see below:
As you mention only in the 27 HP edition,
I hold one of thes 65´s, with original papers from the Bmw claiming it
to be 50 Hp, i know that probably 100 pcs. vere made with this engine,
mostly used be Danish authorities such as Millitary Police, as you
also mention 1727 of the 65 GS, were made, well, I´ve heard 1721 to be
exact, but also heard another version saying a little more than 1300
were produced, this figure probably excludes the app. 400 pcs. delived
all in all for Danish authorities, Army, Firebrigades, Homeguard,
Rescue, etc. Best regards, Niels Henrik Nielsen
