DIAMOND (OMN) gil Caster Set by Gillinder & Sons Incorporated (Philadelphia/Greensburg-PA, Operated: 1863-Today), c.1870
NOTE: Sid Lethbridge 2022: [drawning] cut is c1884, labelled in Contributor Line. They appear in the c1876 and c1870 catalogues as well. The cut attached here is from the c1870 catalogue. I am thinking these caster bottles are a standalone as they predate the Diamond tableware line.
