Hi HT6 and tiger

Yeah, I'm pretty sure we have not seen one of these before.
This ad (extract) comes from Sept 1962 - so that fits in nicely
with it being a J62 for the 1962-63 lawnmower season (and beyond).

p.s. HT6 has given important safety advice about these cased springs.
I am told that an unaware repairer removing the spring from its casing
would initiate a moistening process in the repairer's undergarments grin
