I note that Salvimar has added new models to the Predathor range. You can now get a single power 55 cm gun with a camo tank which is called the "Storm" and there are three single power guns in 40, 55 and 65 cm which are the "Rock" model. Interestingly the latter guns are supplied without a hand pump, so that will be an extra purchase. There is now a 55 cm "Dark Side" model which is also single power.
