His two Targetmasters are:
Boomer, the blue Targetmaster, who has a gold gun on his right arm and a 5mm peg on his chest. I like the chest mounted pegs, you can pretend that they're cannons. He's got red painted highlights on waist & upper legs. His single gun barrel folds out from behind his legs to turn him into a gun.
The yellow Targetmaster is Ricochet. This is the only name to be used for a Targetmaster gun and a Targetmaster wielding robot. He too has his peg on his chest but features no obvious moulded weaponry. He has off white paint on his arms & lower legs with a blue painted midriff and face. He also has a single barrel on his weapons mode which again folds out from behind his legs.
To transform Quickmix into robot mode, start by folding the rear wheel and base of the vehicle out to the sides and up to form the arms. Push the mixing barrel down locking it in place when it's whole length is horizontal. His head should pop out when you do this. Fold the front of the vehicle down & forward 180 degrees to form the lowers legs - the front grill will fold up to accommodate the upper legs. Stand with the underside of the vehicle facing you.
Quickmix's robot mode is mainly red with white arms and chest. The head is again, like Landfill, a great sculpt, and similarly ruined by some pale blue paint which hides the difference between the top of his face plate and his eyes. In theory his knees bend together as part of the TF but the only real articulation here is at the shoulders allowing the arms to raise. He's got 5mm peg holes in his hands to allow him to hold his guns (I mean you wouldn't be silly enough to make a toy like this who couldn't hold his guns in his hands would you?). He can either hold his guns in each hand or combine them into a dual barrelled gun or a large gun with stock.
Ignoring the non turning barrel and the smooth wheels, this isn't a bad toy. What happens to the mixing barrel is clever, much better than leaving it on the toy's back.
Quickmix was sold in the USA & UK as a carded toy in 1988. He was not sold in Japan.
