Roco M60A2

Roco M60 tank hull with Roco M60A2 turret.

Roco sold the turrets as separate sets.

They were kits that had to be assembled with rather a lot of little pieces.

Comparison shot of M60 and M60A2 tanks.

This is the M60A2 by Tomy, also in HO scale.  Note the barrel is the early version, Roco included the early and late versions in their kits.
