It's available in the shop in KWK (the alley) 小巷, which sell PRC toy, minibike, RC stuff...etc.
You'll first see it among the boxes of 'snow-leopord' (M48) but look closely one of them is a M41.
But I believed this one doesnot come with 'smoke & sound'.
According to comments in oversea forum this model is not to the scale, M41 is a light tank but this model has the same size as a Tiger-1. Thus it would be 1/14 instead of 1/16.
