Pair of antique pewter inkwells, with SO marks to the undersides for the Stationery Office.  They have flip lids which reveal glass liners, and they have 5 pen / quill holders.  They measure just over 8cm in diameter to the bases.  One of the glass liners is also Stationery Office marked, but the other isn’t.  As per the photos, there is some scratching to the bases, plus some ink staining internally and to the lids – one blue and one red.
