Jim-
Here are the new Century Jet retracts for the B-25...this is a nice durable set of retracts for $365 and the kit includes everything. I threw the wheels on to get a little more pespective. Wheels are 3.50 mains and 2.75 nose. I also included the new bomber pilot busts that just came out. I know you already have purchased this stuff for your B-25 but I thought others might want to consider other options. These retracts are custom made for the H9 B-25.
