Missing mullion end cap window

[HannahJ]

Hello I have recently moved home and the house has French style windows in the bedroom. It is missing the mullion end cap for the bottom of the window.
I can not see a make or product code anywhere. I am hoping someone can identify it please

Can you take a photo of the internal glazing bead, the bits that hold the glass in

The house was built by persimmon homes around 2002 if that helps at all

Closest match I can find is from a system called Duraflex but is no longer made however, compare your 3rd picture to this screenshot, maybe it could be adapted to fit if your problem is the daylight gap and the draught blowing through.

I've been going through my archives all day in between jobs and I don't have any firm ideas, sorry
