These cufflinks, which date from the 1920's most likely, have never been used and are on the original jeweler's display card! The marquise shaped links are about 2/4" in length and 1/2" in width.
The front link has a combination of machined pattern and hand engraving, with a rectangular cartouche for engraving. The back link is plain. While unused, the plain surface does show the effects of 75 or 90 years of display and storage, with minor surface scratching. The patterned surface on the front hides the shop wear on that surface. The backs have some discoloration and I have not attempted to clean this. The links have a gold finish and I assume they are gold filled or rolled gold plate.
These ones are hallmarked PSCO, for the Plainville Stock Company. The rare opportunity to acquire a vintage pair of cufflinks in rare condition.
