That is probably an Aurora Bonzo. I don't think Testors made a Bonzo. They did a Cosmic Wind that was the same exact airplane as the small Cox Cosmic Wind, just different engine mount. Testors did a larger Cosmic Wind also. I go an email alert that you posted on the yahoo 1/2A group. Do a search on that and you will find photos that someone posted for me of the two 'Winds." As far as decals go, you may try searching under the Aurora manufacturer.
