1952 RE Model S

and yes alot of books dont mention the export model

I suppose that begs the question - did ANY mention it ?

What now makes it 1952, and not 1951 ?

[cruise98]

Made from 1951 1952 1953 mine was sent Western Australia September 1951

Here is a 1951

In 1950 we were exporting anything and everything we could to earn Dollars after the USA dumped us in the crap.

If there was a demand we tried to fill it, but there was also a chronic shortage of materials, power, everything.

There was a big demand from down under for british bikes cars etc, so if  a factory could cobble a number of bikes together, that's what they sent to the other side of the planet, often knowing full well that there would be little or no spares back up or customers complaining at the factory gates.
Same reason a lot of experimental or dead end racing bike projects got shipped out.

debatable ethics but needs must where the devil drives.

Its a mistake to imagine everything made back then was pearl handled hand  made works of art.

Yeah so true i love the bike i know its not so sort after but i dont mind as long as its not a harley i love the brittish bikes

[mini-me]

any bike is better than no bike, and even the bottom of the range stuff is part of history.

That brochure pic for 1952 certainly nails the Miller part of the electrics.
Interesting that it mentions a Lucas Magdyno as an option, if you can't make one fit ?

That tank badge looks later though, wasn't 1953 the first year for them. ?
That exact pic is in Gordon Mays' book as a 1954 model.
(noting previously that he has nothing for the Model S for earlier years).

1951 52 53 export model
To change to a lucas there was a list of stuffed ypu had to change including crankcase

[cruise98]

Just hoping someone might know im missing the front chain sprocket off this 250cc its it has a keyway and shaft has thread on end and thats about as much as i know

To change to a lucas there was a list of stuff you had to change including crankcase

Thats what i had suspected.
Not a very good strategy by RE, methinks.

Suppose it keeps the deluxe models more exclusive like...

Have you tried contacting Hitchcocks about this ?
They would be your best hope.
If they have a prewar parts list for an S, it will have a part number, and they can see if they have some, or the specs for having some made. And the nut to hold it on.

If they don't, engineering/agricultural shops keep sprocket blanks.
You'd have to measure the taper angle - they come often in std sizes, not as random as you'd think, and measure the chain size, and have something suitable made up. Agricultural places do this all the time, the price of original farming parts can be absolute murder, but cheap to make up.
The depth of the taper is the only tricky part, and the keyway depth.

Finding an old sprocket someplace would be rather helpful - and the sprockets for the larger cc models are interchangeable to some extent, so maybe the smaller ones are too ?

Hi Cruise
Could you measure the radius of the dynamo cradle seating as some Miller dynamo's are/were a different diamater to Lucas,
It might be easier to find a Lucas E3HB than a Miller ?
Some while ago I fitted an Alton (Lucas size 3in.) to a Vincent that originally had a 3 1/2in Miller
Similar to your RE the cradle was part of the crankcase
A conversion sleeve is available for the Vincent's, eccentrically bored so you can adjust the sprocket mesh
It might provide a solution for your RE ?
Have you asked Modak about a dynamo? Lucas or Miller

Hi John the cradle isnt there unfortunely . who is modak ?
So found the 51 to 53 were export only they used parts left over from war they used g frames 350cc rigid some went through with girder forks but most telescopic then in 1954 model S was sold in UK for only a short time along with the clipper as a cheaper option

[R]

Where did this "wartime" info come from ?

I would have thought that was a little unlikely ?
1951 is a long time after WW2 to have bulk parts left over from. ?
I've got a 1945 Model CO, and it was a new build then, not refurbed WW2 parts.
They are in the brochure as such, alongside said refurbed WW2 bikes.
They wouldn't have built too many Model G's during WW2 either ?,
they were mostly the C and CO and DD.

Another complication with that G frame theory is the front and back engine mounts on Model G engines are quite wide, 3" at the front and 4" (?) at the back.
Your engine mounts would be narrower (?), how did the frame cope with that ?
Of course, Model G frames could have been built with narrower engine mounts...
(Would that still make them Model G ?).
??
Cheers.
