Hi Guys
Not sure if this applies to the TankArmy product, but I got an HL M26 late last year, have just started working on it, but still haven't open it up yet, but what I've noticed is that the plastic tracks are hollow - on the inside - and it now has single pin tracks (2nd pin is just a moulding). Otherwise , externally its the same as my old HL M26.
