RE: M113 makers in 1/16
Only one I have seen is Tamiya 1;35. Had to scratch make an M-59....there are NO models of it at all. Not even a Brit APC to use as a scratch base. Only thing for 1;16 is to use the HL M-41, reverse the chassis and build up from the tracks. Outside of HL off scale, at least the suspension is there.
