Series MM rev counter?!
I was wondering if anyone had seen one of these before? It has the same mountings as the MM speedo and is cable driven.
<br><br>
Maybe it was offered as an extra for those ALTA equipped MM's?

What an excellent bit of kit. Do you have a photo of the gearbox end of the cable drive? The fittings look the same as the speedo so maybe it replaced the speedo for circuit racing. Does it have perspex side panels for inst. lighting?

It does have the panels for illumination! I do not have the cable for it, when i said it is cable driven i was only saying that it was driven by a cable rather than electric <br><br>mike.perry wrote:What an excellent bit of kit.

That's true, silly me.
I've seen a reduction gear for a mechanical rev counter years ago but I couldn't remember how it fitted.
I still think you could test the rev counter by swapping it with the speedo and driving slowly to see what happens, that's assuming it is geared to turn the same way as the speedo.

Comments from Graham Holt
1] MM Rev Counter: Confess that I have NOT seen one of these before.
Can only assume/ suggest that this item was perhaps introduced in the
1950's when there were quite a lot of MM's being used in Club Racing at
Home and Abroad - check out a few copies of Motoring mags from those days and you'll see what I mean. {Guess it would also fitted an early S11 - the mind boggles!]. As all road cars have had to have a speedo fitted for 'n' number of years, I believe that if this instrument was used instead of the speedo, then it would have been fitted only for use on racetrack - unless the speedo was retained and re-located elsewhere.
Certainly the likely position for the rev Counter would be, in front of
the (racing) driver = in the Speedo position. Would further suggest that
perhaps the "guts" of the rev counter were fitted to a standard Speedo
casing in order to save expense and this would explain why there is a
cable drive take-off in place. Can we find out if there are any elec
connections or wiring in place anywhere? Not sure of status ref method
of connection that would have been used in the 1950's for this item, ie,
mechanical from engine or electrical from ignition system. No doubt there
will be further comments from other contributors on this subject and will
look forward to seeing these, soonest. Maybe, it might be possible to
make contact with someone in the instrument repair business who may know about/remember instruments from the 1940's thro' to 1960's.

That looks perfect for the job but if you look closely you can see the join where the piece on the left has been let in so probably a homemade set but perfect all the same. May have a go at making a set up as i have a *few* spare dash covers!!oliver-morrisminor wrote:I don't know if this helps but I once saw these advertised on ebay.<br><br>
