Chris Schwarz over at Lost Art Press posted a blog entry yesterday with links to three moulding catalogues you can download. The catalogues range from a 1938 catalogue using the old Universal system where the profile numbers were a fairly universal ( at least within the U.S.) numbering system called the 8000 system. The original numbering system begun in the mid 1800’s used a three digit number starting with 1. You can see how the inventory of stock moulds changed over the years as manufacturers offered fewer and fewer profiles. The mid 1800’s catalogues included over 600 different profiles which would dwindle to less than 50 in many catalogues in the early 1950’s.
Here’s three examples that show the slow loss of the variety of stock stop moulds, the first from the 1890’s catalogue, the second from a 1938 catalogue and the last from a booklet from the 1960’s.
You can read the blog article and download the catalogues at this link. Special thanks to Chris, Eric Brown and Thor Mikesell for sharing the research material.
