I removed the Bandai seats from the T-34 and replaced them with the Hobbyboss seats. The HobbyBoss exhaust pipes were also used after removing the air cleaner parts from them. HobbyBoss would have you use both styles of air cleaner but I think it was one or the other. Much more detailed. I used the Bandai 76mm shells, pretty simplified and showing a lack of skill in getting the copper color, I need to work on that. I'm thinking polishing powder may be a better way in order to get the sheen I want. I don't think they will be very visible. After adding some compressed air tanks the the hull was closed up. Put on the first layer of exterior paint, I'm using Model Master 34102 for that.
