It's dimensions are 18.5cm long, 19.5 diam, 33 coils of 3.1mm wire. No breakages or kinks, evenly spaced between coils & smoothly ground ends. It looks in quite good condition but would appear to be too short when compared with the springs I've come across before, some of which have several cms preload.
Looking forward to your learned opinions on this matter.
Thanks, Glyn
