I still do the occasional Roco minitank. Newer released are very detailed. Theres a new tooling out of the German M48A2GA2 variant,

It could easily be kitbashed with their more primative A1 variant. Now if they would just rerelease theyre M60 bustle rack and M60A2 conversion

lemme give you a hand :
small but beautiful, I'd say. The hull is the old dog and needs a lot work. Even in this small scale, but it's still a lot of fun ... Same goes for their M60A2. I got one from way back in the '80's .... Have to check if I can find this little bugger locally

But you notice it got the full detail package. With all the stuff. I wish they would rerelease the M60A1/A3 with the rack , smoke grenades and headlight. Plus now Preiser has the good crew guys
