Sorry I was talking about magnetic drive on the speedo
dial/needle, i have not seen the inside of corbin etc and
wondered how the dial drive worked on the inside of the cup

  The scans illustrate rear wheel drive for both the SW as 
well as the JM.  It makes no sense to drive the speedo from 
e mag as engine rpm bears no relation to road speed.  
Speed at 2000 rpm in first gear is much different than 2000 
m in third.  It is however, not uncommon for tachometers 
to be mag driven.  I know of a circa 1918 Henderson racer 
with a mag driven Corbin tach.  I'll try and obtain some 
photos of the set up ... Perry

thanks perry for the info what i have is the 84-b can you
tell me was this the only mag driven speedo offered for
motorcycles, since the J-M sayes nothing about mag drive?
and i think SW was the only one using mag drive back then?
am i right about this? Thanks for the help iv found more on
this speedo in the last day than i have in 2 weeks of phone
calls allso thanks for the photos that i can read my hard
copy's are still in the mail.

  Darrin - I believe the speedo you have is colloquially
called the "potato masher" after the WWII German hand
grenades.  This (or similar) is probably what the 1927
dealer book will show:

I'm no expert, but I don't think these were fitted at the
factory by any of the manufacturers.  They were just an
aftermarket accessory that could be mounted to any
production bike of the day.  Certianly the book that that
scan came from listed mounting parts/details for Harley
and Indian as well as Henderson and Excelsior.  
  I believe the 100mph JM max hand head:

is what is considered to have been standard equipment on 
the 27 Hendersons ... Perry

Hi Perry,

You are very perceptive and correct in your assumption that
the 1927 Deluxe was fitted with the J-M speedo.  I have seen
remely unmolested '27 (except for a lousy
overpaint)and another machine untouched for years both
fitted with complete dashes that had that speedo. I also
have one for my o/p '27.  Henderson used those God awful
switches in '27, Super X as well.  Hopefully you have that
as it is the harder item to find.  Strange they deviated one
hen went back to the Corbin for the '28 model.  If
your bent on the judging, I would go with J-M.  Also you may
someone napping, not knowing what that speedo is, i.e.
maybe not m/c or aftermarket and be able to grab it for
shorter money than the Corbin.  You also need to be aware
that the angle drive, internal ends and cable ferrels are
also different than Corbin.  This is not a major problem if
you go to auto swop meets where pre 1930 parts are sold. 
Check Hemmings as well.

Steve

  Would anyone like to weight in on what is the correct 
speedo for a 1927 Deluxe?  The speedo in the brochure 
clearly isn't a Corbin.  Were bikes delivered as shown
in the brochure?  Is the correct speedo a Johns-Mansville
(that's what the brochure photo looks like to me (which 
by this time may have been the JM model Stewart-Warner))?  
Is a Corbin accepted in judging?  Thanks ... Perry
