The B8M1 rocket launcher carries 80mm S-8 unguided rockets that can come in a variety of types. It is still in use by various countries and on various planes. Advanced Modeling has produced a wonderful 1/72nd scale version of this weapon to upgrade current kit parts or add something different.
The resin comes with enough parts for two rocket launchers that each consist of three parts - the main body, the nose cone and the back shroud. Simply cut the parts from the casting blocks and make sure they are square. Glue the parts together and fill any seams (I had almost none as the fit was good).
