I recently acquired a collection of vintage reproduction seal matrices cast from original molds circa 1940-1960. These matrices were part of a larger collection, and I was delighted to acquire them. The seal matrices were purchased in England and cast in resin. Each one is different, and some are double-sided. I haven't had the time to research them, but it can be done with some time and effort. While I purchased these in England, they could also be from France or Belgium.
