Re: Is this an ariel ?

If the number given is the engine number then I agree with Tony that it would be a very early Abingdon engine. I have 6 recorded between 5000 and 6000 but none lower and all but 2 of these have been reliably dated to 1914. I can't get the link to the other photos to work.

Re: Frame, Engine and Contract Numbers

The only conclusion is that your mudguard is not the original for the bike. The contract number on the mudguard covers engines 21,501 to 25,000 and frames bewteen 31,751 and 35,250 despatched between 29/10/42 and 5/4/43 but your engine is from C 8,722 despatched between 2/11/40 and 4/3/41. Typically...

Re: 1957-58 tank centre strip

Thanks Simon, I had seen that post but it appeared to be Bunners first impression. He doesn't seem to be a current member so I can't contact him. We have just heard that the shipping of the tooling from our previous supplier in Canada will be about £600 plus £260 to buy the tooling, all of which mak...

Re: Square Four Logo

It is possible that bikes that went to Australia had the logo painted, if asked for by the importer, there are numerous instances of special requests by certain importers but I do not recolect ever seeing this remarked on in the despatch books. It may have been carried out by one or several dealers ...

Re: NH350 Gear Box Pawl

The pegs were originally a tight fit in the housing but a little wear will not cause a problem, the fit should be rectified. The likely cause of it jumping out of third is worn dogs on the layshaft clutch 3141-34. There are only a couple of symptons associated with gearboxes, jumping out of gear and...

I agree with Paul, well I usually do, I have seen a few with paint in the recess but too few to be likely to be original.

Re: 1937 VB 600 handlebar rubber bushes

Correct, there should be a small screw in the centre of the 'bars to limit movement, however by the time the screw meets the bracket the bars are much too low for normal use. The 'bars should also have knurling to assist the rubber in gripping the 'bars. I believe that there is a rubber 'glue' that ...

1957-58 tank centre strip

Does anyone have any experience of the Indian made tank centre strips? Is the fit and chrome OK, if not can they be altered to make them work withour too much trouble?

Re: Amal 376 carburetter

Jurgen Wilms from Berlin showed me a carb that he had sleeved and repaired the top thread by boring the body out and fitting a brass sleeve incorporating a flange at the top with a new thread to replace the damaged one, in the shape of a flanged liner. Difficult to describe ....
