Is interesting to see that the Kubinka Sturmtiger has a bolted on lower front hull glacis. THe Tamiya kit does not offer that.
Meng does offer a set of Nuts and bolt caps that will work on replicating that.
I think the set is Set D.
And AFAIK, only Ryefield Models offers a kit that would replicate the Kubinka Sturmtiger.
Trumpeter makes a 1/72 scale version of the prototype with the rubber wheels, but you can make a 35th scale by cobbling the really roadwheels off the Tiger with the Tamiya kit, like Wade mentioned, so that’s not a big deal.
