Ebay currently has a Berling E-41 magneto - number
2484585116. My 1917 parts list only says 'Berling' - it does
not give a part number so I DO NOT KNOW IF THIS IS THE
CORRECT MAGNETO FOR YOUR MACHINE but thought I'd bring it to
your attention anyway...Steve

 Yes he is all right and the sense of rotation is right and
the attacks are correct, you speak very well, in lack of
other magnets I use the DU4. . . it is new and it works very
ell. Thanks to all for the suggestions

The 1920/21 Model K parts list indicates a Simms magneto as
being correct for these models. But someone may well have
fitted a ZF4 to a 1920 K - I did some work a couple of years
o on a 25 Deluxe which had been fitted with a Lucas
(British) mag - that's definitely wrong but it ran
beautifully! I agree with Ken - if it's clockwise rotation,
shaft height correct and bolt hole centres correct, then fit
, ride it and enjoy it! You can always fit the correct mag
at a later date if one turns up! Safe riding ... Steve

Yes, I have checked on other motorbikes, the magneto DU4 is
for Henderson 1914 and ZF4 is for Henderson model K 1920.
Thanks for the confirmation for my doubts,  I have been
wrong in to buy these two magnets, but they was the only
ones that had in sale . . . . . does someone want to make an
hange?

Hello Devid , As long as the magneto is the correct rotation
ckwise) and platform to drive shaft hieght , it should
run ok , Bosch are usually good mags , Ken

 Have I found a Bosch DU 4 and a bosch ZF 4 which the most
correct is?

Hello Devid , I think the orriginal magneto for the 1917
Henderson is a "Berling" BUT I'm sure a later "Splitdorf" or
" will fit and work as well . Best of luck , Ken
