Toyeast has these under the WSN name. WSN is the RC division of Trumpeter. These are T34-85 RC tanks from Trumpeter molds that come 90% assembled with all the RC stuff installed. The Marui tank group on Yahoo caught on that these are the identical tanks to the Mitsuwa that is being sold for as much as $280 shipped by Rainbowten and Hobbylinkjapan.
I got lucky and got mine for $75 shipped before Toyeast went up on them later this week.[8D]
Go to www.toyeast.com and search for WSN and\or T34.
You can pay just as much for a Trumpeter KIT nowadays.
Go get 'em!
Is this the same as the trumpeter kit but without the interior?
In other words, the same exterior quality? What’s included, the ad doesn’t show.
I’m interested in the kit from trumpeter, but I want to model just the exterior.
Whatever you could tell me would be helpful.
The same molds were used as best I can tell. The sprues are marked “Trumpeter”. You also get a RTR tank with link tracks, etc. in the bargain.
The last time I looked, the tanks were up to $100 shipped to the US from Toyeast. YOu can pay triple that on Ebay or from Rainbowten if you are so inclined. 
There is an ongoing discussion in the Tokyo Marui 1/24 scale Yahoo Group http://groups.yahoo.com/group/MaruiTankGroup/
