Speedometer correction box
Discussion
I have 2 of these speedometer correction boxes, not sure if anyone uses these anymore. They come with a set of gears and a chart so you can correct your speedometers without stripping and calibrating your original. Used when you change gearboxes or differentials etc. Are they worth anything to anyone?.

I could have used one a few years ago. What a fab little kit!I will check tonight I have all the gears for both sets. 1 set is in the supplied box the other is loose but all gears are marked so you can still find the correct one when building the gearbox.
Here is a couple of pages from the manual to give you an idea of what to do with it.
These were made by US Company who no longer exist. I assume they must be rare in the UK.

What a wonderful piece of kit; please don't destroy it by selling it piece meal- yes it's anachronistic but wonderful in it's tactility, "usefulness" and the history attached to it.
I bought my son, who's an architect, a Craftsmen's Fowlers 12/10 Calculator, as a gift for xmas- absolutely bally useless in what he's doing, he'll use a scientific calculator and get far better results but heh! why drive a Triumph TR4 or a Citroen 2CV or etc etc?
Wonderful - thank you for sharing.

For years I've put off having my Riley's speedo recalibrated due to none standard wheels and tyres. It's so far 'out' that I use a speedo app on my mobile phone instead. This gizmo would completely solve the problem! If you're wanting to sell, please PM me with a price.
I used a bicycle speedo for a while when my speedo cable broke and couldn't be bothered to renew it at the time.it worked well with a magnet target in the wheel rim,...I was surprised that the readout went up to 255mph or something like that.
I've got a whole garage full of unused stuff like that – 
it'll come in useful one day...

Quite popular among the vintage fraternity. You can get a cycle speedo with large digits, yet the small overall size makes it easy to mount in both a well hidden yet readable place. Calibration is pretty easy too.it worked well with a magnet target in the wheel rim,...I was surprised that the readout went up to 255mph or something like that.
Not widely known, but speedos only became compulsory in 1934 and many budget cars and motorbikes sold before then did not have a speedo at all.

I've told this tale on here before but I,ll tell it again.The vicar at my school had a Brough Superior (well he had five and two Morgan 3 wheelers), not that I'm saying the Brough was a budget bike mind!
The Brough didn't have a speedo so me, 13/14 years old, asked him how he knew what speed he was doing, he replied that as the lamp posts in a 30mph areas were space a certain distance apart he had worked out that when the bike was firing at every lamp post he was doing 70 mph!

Sorry for the delay, I have only managed to find one of the kits. I definitely have another so will continue to look. I have had a lot of messages regarding these and while looking I found the receipt for one of the sets it cost me $100 plus shipping so I will take £50 plus postage.
Hi Getsis, hopefully you got my PM a few days ago expressing interest -I will certainly take one for the Gordon-Keeble at £50!Hi Getsis,
do you still have one of these correction boxes? - I bought a KS Trip Counter recently to use it in my MGA. The original T-piece did not fit with the car. So we installed a Halda T-piece. Now the trip counter runs but gives completely incorrect distances (so not sligt differences but half of what I drove).
Any hints or correction boxes / tools are welcome. Also if you have experience with KS TC in MG cars.
Thx!!
