There are 520 bikes with W/NG frames listed on the register, 29 are Navy, 53 RAF, some will have other engines fitted and a few will look nothing like W/NG.

Wow!

Thanks, Vincent.
Magnificent.

It'll take hours to observe all the details.

The disassembly has begun; so far, no unpleasant surprises.

Please use this forum's way of showing pictures!

Below you see 'Full editor & preview'

click on that .

Below this field you see 'Options' and 'Attachments'

click on Attachments.

Now a small field opens that says :

If you wish to attach one or more files enter the details below. You may also attach files by dragging and dropping them in the message box.

click on 'Add files'

this opens all the files in your pc (with a Apple I dont know but I presume it works similar)

Go to the file you want, select it and click on 'Open' in the low right hand corner.

Thanks.

Vincent,
it's really very interesting to look at the details in the photos.

Two photos caught my eye:
The Ariel with the tank number C4694544.
By relating the numbers to the frame/tank at the start of the contract,
my "Siren" would be the 59th.
In theory, its tank number would be C4692958.
It should have this final configuration, correct?

The other photo is one used by an American; it's the first time I've seen a British vehicle bearing the typical X marking on "parasite" vehicles of the American army.

I'm afraid you can't relate tank numbers to frame numbers in that way - we know that tank numbers were applied around the time of dispatch, after the machines were built. It is very clear in the dispatch books that the frame numbers are anything but sequential and adjacent machines in the books can be hundreds of frames apart.

Okay, so there's no logic to it.

For the registration number, ideally the tolerance should be within 100.

Yes, thank you!
And your frame looks very good, all the original brackets look to be present.
Keep us informed about the progress please !

On the front fender, on the outside, there are license plate brackets.

Inside, other holes have been filled.
My question: which part is still usable? The existing brackets? The four filled holes? Or neither?
