This set comprises six runs of finely detailed resin track (more than enough for one tank) and two paired drive wheels to fit the track. As well as the A15 Crusader, the track can be used on models of the A13 Cruiser Mk V Covenanter (note that it is not correct for earlier A13 Cruiser tanks).
OKB Grigorov tracks are exceptionally easy to work with, After removing them from the sprue, they may need some slight clean-up (though they usually don't), and this is best achieved with an inter-dental toothbrush. The resin is malleable and will curve around wheels naturally - this can be encouraged with the gentle use of a hair dryer. Though this set is shown as 1/72, we have successfully used them with1/76 scale models too.
