Don, the jump at Glen Auldyn is still in existence (there are much videos taken from there) but it has been "tamed" (we italian say "addomesticato"). From what I've read it was a much higher jump than it's now. This is what Ray Knight writes about it in his 1974 "TT racing":

"Now resurfaced, it used to be a real nerve tester and spectators on the wall to the left hand side could see some really wortyhwhile 'wobblies' as the bikes landed and immediately turned right as they landed. It is still maybe worth a brief visit but it is not so spectacular now".

A similar concept is expressed in the 1989 "TT rider's guide" by the same autor.

So, yes. The jump is still there but according to Knight's opinion in the past it was a much higher one. The difficult thing in that point is that there is a very fast right corner just after the jump. From the 2004 camera bike from the lamented Britton we can see that the speed in that corner is well over the 130 mph. It's a flat out corner.

Many thanks in advance for the Graham photos! But if you prefer you could simply e-mail me a scan of them.
