This picture is to show the differences between the tops of my Vectors’ caps.
Parker Vector ‘Flighter’ FP
Made by Luxor in India in 2019.
The oval depression in its cap is filled with black plastic, to match the black plastic trim on the cap, and that at the distal end of the ’Flighter’ barrel.
Parker Vector FP in black plastic
This pen was made in Newhaven in 1994.
The oval depression in this pen’s cap’s top is decorated with what looks like a piece of white cardboard/paper.
This enables one to rapidly distinguish the fact that this is the Vector FP from the next two Vectors (RB & BP) without having to remove the pens from one’s pocket.
Parker Vector RB in black plastic
This is another Newhaven pen, but dates from 1985.
Note that the insert visible inside the oval on this pen’s cap’s top is made of shiny ‘white metal’ (steel?).
Parker Vector ‘Flighter’ BP
This pen was also made in Newhaven in 1985.
Its cap-decoration appears to be made of brass. Or, at least, it is ‘brass-coloured’.
