The new spring arrived this morning from

Not bad as I only ordered it yesterday £20.50 posted so I took both of the guns apart and the new spring is slightly longer than the mk1 spring so that one must have been replaced at some time it was one heck of a squeeze to get it in but the gun is so much better than it was with the old short bent spring that was £20 well spent.
