Tamiya T-34/76 Model 1943 ChTZ Version

Tank Work Shop makes some nice resin T-34 details, you can see a nearly complete list at R&J Products.

if you already have the kit you could try Eduards site and do a search for t34 (there search isnt that good to pick up chtz)
there site is http://www.eduard.com/ they have one on there with a couple more T-34s
its on page 84 on the product list for armour kits

if you havnt got the tamiya kit yet, have a look for the Dragon kit, its very nice

I believe Eduard makes a set, but this kit is basically their 30 year old T-34 with a new turret. There are more accurate T-34/76s kicking around that do not require $20 aftermarket parts to superdetail.
