Paul from SWISCO responded:

I think the key stamp here for your cottage Narroline window the one that's covered with a staple. It's a little hard to make out but it appears to be #R13-927; if so, you will need our 24-R13-927 and the 24-L9-1327 for the opposite side. You should confirm what the stamp reads just in case, though.
