Turned out the sills had been done in the last 2 months.
These are the previous owners pictures that I've just copied to my dropbox and within the main folder there is another calls sills and mirros I think.

Will get around to taking some pictures when it's had a proper clean.
Was covered in salt / grit crap from the drive down which I've washed off but hasn't had a serious clean.
