Autojumble / Re: Wanted, Dolls head gearbox

You are being the serious rivet counter here !
There was more overlap in these things than you suggest, this has been discussed on various Norton forums, bikes keep turning up with non-catalog equip but which match the factory records,
so Nortons evidently used whatever was to hand sometimes to turn out bikes for sale.
The dolls head box lingered for the 500T and manx for example, for some years too, so were stocked for years after most folks say they were gone...

And, strictly speaking, approx 95% (?) of '1946' model Nortons are ex-WD bikes,
since this was the year of 1st registration, and refurbed ex-military bikes were swamping the market. (military bikes weren't registered, but they did have to have a military number).
Never mind that they were manufactured during the war years.
And yes, the dolls head box was suggested here precisely because his bike looked to be an ex-military bike, without this having been confirmed yet.
Makes finding a suitable box fairly straightforward.
Actually helping folks is what these forums are all about...

For a fee, the NOC can check the factory records and see if the build spec was recorded.
Just knowing if its a civvy or ex-WD bike would about give the same info, since postwar civvy bikes are easy to date precisely from the numbers, this info is well documented.

I can't help thinking you are talking about the upright box - for 1946 & 1947 - enclosed and with the round clutch adjuster cover ? 

Would the OP here bike have had such a box, they are generally shown with the dolls head box that early ??  Did we ascertain also that this bike was manufactured in 1946, and is not a refurbed WW2 bike 1st registered in 1946 ?

Fitted a new 2 stroke plug, petrol down the hole, nothing.

If petrol down the plughole (how much, just a teaspoon full ?) with a new plug doesn't produce even a pop, then the problem is in the ignition or ignition timing.
Checked the timing, tried cleaning the points ?

btw, the fuel down the plughole should be 2 stroke fuel - ie with a dash of oil in it.
Or it washes the ring seal off the bore, and out of the main bearings...

You should try a NEW plug, even if its not quite the correct grade, as a short term try.

I learned that one very early on in dealing with old bikes - a spark outside is no guarantee of anything when it comes to reliable starting. And your story sure reeks of that....
Have fun !

How are they any different though ?
Even a rivet counter would have trouble knowing what the correct number sequence was...

The near 100,000 boxes built for WW2 bikes aren't so different ?
Likewise 1930s versions.

Graces Guide has 2 or 3 lines about Albion Eng
Name and address, a starting point ?

Would the motorcycling weaklies have ever covered them ?

We diverge...

Be a little cautious about expecting/attempting to swap internals between early and late boxes ?

The tooth form changed somewhere along the line, so it was always recommended to change gears in pairs - and also not mix old with new. And the bushes went from solid bronze ones to sintered bronze, so the installation and running clearances are 2 separate instructions in the manuals.

There may not be a lot of difference, but if there is.....

Didn't someone post a link recently to where this was online ?
And some types of scans are searchable even.

Also, searching in scans of local papers could also produce a result or 3. ?
Viewing the motoring section or adverts for them can often turn up 'stuff',
especially in the early years where the local press was the only way of getting the word out.

It might also be helpful to know a little history of this.
Has it done a million miles of faithful service for you (!),
or have you just obtained it like this ?

Whatever, this needs serious investigation, as Ian says.
Forcing it is rather likely to cause (further) damage.

Yes, and I was going to suggest have you tried stripping off the handpainted efforts, to see if there is any surviving maroon underneath.

This bike's pics appear in a number of places, with varying shades of red/maroon.
This pic seems rather bright, it would generally be a shade or 2 darker.
(Reds are notoriously difficult to photograph)

The RAL paint numbers in the low 3000's cover dark reds, see if any match anything you can find. ?

The laydown box is later than your bike, and won't fit - the mountings are different.
So you are looking for a dolls head.
Ex-WD ones are fairly common, but make sure its in good condition.
Your present box is purely SturmeyArcher, as supplied for a Norton.

The Burman manufacturing connection is largely unknown to most, and not generally referred to in connection with any Norton gearbox.  Burman boxes are different.

Your best bet is to take an original piece of maroon excelsior in to the painter/ suppler to have it matched.  They often have books of colour chips, which you can choose from.

Unless someone here can supply a code - which often don't translate well across different paint manufacturers. 

I'd suspect this would be a fairly good match - but is for another make.

The dolls head boxes still had quite a long throw, with that long gangly gearlever,
even with all play taken out of the linkages.
It was only the shorter lever of the laydown box that reduced the lever movement,
and the even shorter 5" lever of the AMC box further reduced the throw.
But the footrests need to be suitably positioned to be able to take advantage of this.
