It was the receiver box from the Mugen super athlete that we used to use. The trinity box is almost too small. I always preferred the RPM box. While it does take some drilling, the NTC3 box is popular because it is lower and even better was it uses a body clip to close it instead of allen screws. You don't need tools to open it up to change a crystal.
