UPVC window Beading

[OhdearIbrokeit]

Anyone have any idea what kind of beading this is? It was around the bottom window panel of a door, but after an enthusiastic removal it's now mangled and needs replacing. It's oldish so I realise this might be difficult. We'd change the window to a panel if needs be so could be permanently fixed in place, then beading adding. Not sure if there's another kind which might fit?

It will be profile specific so you prob need to know the make of the window
