Engraved on the base "SELKIRK GLASS SCOTLAND PARTRIDGE 91/500". Pink fronds can be seen inside the clear glass faceted paperweight which is beautifully engraved on the facet with a Partridge in a Pear Tree (as in the First Day of The Twelve Days of Christmas) and 1979 (year of production). I have tried to bring out the etching in the last, darker photo. No scratches or other damage and still with original sticker on base.
