I have a LH downswept pipe, mainly chrome but patches of rust. I also have a pair of upswept pipes in similar condition but the RH one has some added dents. I am sure they could all be made to suit what you want by a little riding through salt and mud.

Dave, Give me a ring sometime on the number in Cheval. If I know what you are looking for, I can give some guidance as to whether you may find it. The Despatch Books take quite a lot of getting used to but eventually, after about 10 years in my case, you get a "feel" for understanding them...

It does happen, from time to time, that someone gets the original registration number back by means of the frame number. I managed it for Geoff Brown some years ago via the Cheshire Archives but DVLA wouldn't accept that particular approach these days. Richard Thomasson got his original number back ...

The cone in the bottom is purely there to be a guide to get the bottom of the filter over the end of the outlet pipe.

There should be an oil filter in the tank but the 1958 version is very different from the up to 1955 version. It will fit the 1" hole you have but at the bottom, has a cone with a hole in the narrow end which fits over the end of the delivery pipe in the tank. So the late version filters the oi...

If you find which dealer the bike went to, and hence the likely registration authority, and if the registration records have actually survived, you may be able to make a good guess as to the registration number if it was the only Ariel registered by that dealer at the relevant time. Very few registr...

Sorry, I got that wrong. Make that 3 for me.

Re-whitemetaling the old bearings was commonplace about 30 years ago and presumably can still be done by those companies who re-whitemetal big end bearings, etc in classic/vintage car engines. I knew people who did it themselves but I don't think any of those are still with us.

I think the only person doing girders these days is Jake Robbins down in the south-east. You could try Chris Williams at Autocycle Engineering in Dudley who owns Percival and Webb but I think his man who used to do the work is no longer active.
