Andy, that would be the Star Strutter. No surprise there then
The Hansa-Brandenberg DI designed by Ernst Heinkel. Toko made the kit shown in 1/72 but are now defunct. However, a company called Roden have the molds and are in the throws of reissuing them all. Eduard made one in 1/48 but that too is long OOP and no chance of a reissue there I shouldn't think
