It does, doesn't it? Actually, that's what I thought had been done - it had just been cleaned. So my first thought was, that at least I will still have the scratches on the glass. Then when I looked a bit closer, I realised both panes had been completely replaced. I don't know whether they had reached the point where they were considered to be not fit for purpose, or perhaps they were smashed.
Anyway, a new dawn for telephony in Lancaster has arrived!
I am sure it will be no time at all before these two windows become thoroughly begrunged.
