This is Buck Rogers Starfighter and is a Monogram I.P. kit, not sure what scale it is (possibly around 1:35). This is one of the models that i picked up second hand and had to salvage. When i got hold of it it was painted green.
This is the Marauder and is the other Monogram I.P. kit that was created from the series. Again, not sure of the scale but, as with the starfighter, i suspect it is around 1:35 scale.
