Searching for upvc window bead

[diy4win]

Hi, we're missing beading around our window. There are two bits already there holding it in top and bottom - but obviously want to fully bead it in. Have spent several hours on this this morning trying to figure out what bead we need. Window frame says WHS Halo and I've looked at their profiles at https://www.upvcwindowbeads.com and http://www.gablecraft.com/WHS-Halo-System-10-profile.asp but am confused as I can't find a similar bead.

If anyone can provide any help or insight at all, will be much appreciated. Tearing my hair out a bit - couldn't afford to replace the whole unit... and leaving as is looks bad.

Thanks in advance.

Having researched further, looking at old catalogues, it seems it's a WHS Halo System 10 (pre Veka's ownership of Halo and development of System 10 - Veka System 10 uses a different bead).

Appreciate the chances of finding such a bead are less than winning the lottery... but if you don't try you'll never know... any help would be appreciated
