Here we have a previously unknown to exist Jumbo P3 Urchin weight in Green. In all of the 'scanty' Strathearn literature, brochures and catalogs there was no mention of Strathearn ever having made a paperweight of this Urchin series so large. Truely a magnificent weight and a true Jumbo size. Perhaps this was an experimental, a trial or just an 'off-time' weight made by one of the workers and just maybe another one exists in Red or another color.
