RE: Which Tamiya models...
Make sure to get the most recent release of Tamiya kit for use with the Battle System:
Sherman 56014
Tiger I 56010
Tiger II 56018
Pershing 56016
Leopard 56020
Some of the earlier versions do have DMD units but the ealier units do not interface with the full function MF unit included in the recent release kits.
Cheers
