Thanks Dan, we have our priorities sorted !
Rob, the 'hush puppy' track is not a live track, it is dry pin but with moulded on rubber pads to improve running on hard roads. The name is taken from a brand of footwear popular in the '60s or '70s. The two types of track were directly interchangeable, same sprockets etc. The rubber faced hush puppy track came in relatively late so in British service tended to only be used on the specialist versions of Cent as the gun tanks were almost obsolete by then.
We continued with dry pin track longer than almost every other country because they are lighter, easier to work on in the field and of course cheaper. On the other hand they have a shorter life and need constant tightening and can not be refurbished when worn.
