There isn't much web material available for the Arrow, but here's what I have, 
including Classic Trials.  Contact me if you want to add anything.

The MCC's site - details of the Exeter, Edinburgh and Lands End Trials

Andrew Brown's Classic Trials Web Site - a bit too hung up on Marlins, but has some good pics!
Classical Gas - Mike Leete's site - good forum and pics - I don't always agree with opinions expressed!
ACTC - Association of Classic Trials Clubs - page on standard specs for Arrows used for trialling (mine is now modified beyond this into a "trials special" class)
Try this search to see if anything new has turned up on Arrows.  However, be warned - the last one even managed to turn up a sex site reference - I haven't investigated the significance.
