Hello, I've recently learnt that my 1935 250 Comet may have been supplied with the above when new. Could somebody please advise if this is the case or even advisable if not ?
Thank you
The tappet guides sit in tapered bores and are held in by a brigde clamp.
Clamp looks like this:

And a drawing for it:

As noted on the drawing first introduced for the redesigned 350EW around 1927. The clamp remained the same for the subsequent 250/350cc models.

Thanks very much Doug, I couldn't ask for more.
