An historical backround and provenance of these artifacts follows:

As is well known, in 1858, a complete series of copper strikes for the text-sized Caslon Old Face was sold for this design's exclusive use to the Laurence Johnson Foundry of Philadelphia. Among other items, a display containing the 11 point size of these copper strikes and Johnson's original "Starr-process" [Starr's Patent, ca.1845] electro-deposited production matrices were for many years exhibited in a glass case in the reception room of the American Type Founders Company's Library in Jersey City.

Johnson had called the face "Old Style." When its holdings succeeded to MacKellar, Smiths and Jordan, it became Original Old Style. In 1892 it became ATF's Old Style No.71, and after much reworking eventually the design became No.471: the added digit indicates the  MS&J foundry as its source.

In 1986, the following was related by James F. Buckley [1911-1992].

"When the Library was finally sold to Columbia, (it was one of the last things to be cleared out) I was tasked to remove the items which  did not go with that collection, including some artifacts left in the reception area display cabinet. Only the Johnson production matrices for the 11pt  "471" were to go back to the vaults which were now in Elizabeth. I was forbidden to save or take away anything else (it meant instant termination) and the rest of the items that had been overlooked or discarded by the Columbia people were thrown away in the final clean up. My colleague Dick Morroco and I were sorely tempted but we obeyed our boss; his name was Elmo Duff. He had been one of Bullen's most unpleasant "assistants," and had been made head of sales at the time. He didn't last long. Those English strikes, along with the ones from Fry for our Baskerville Roman that ATF bought during the First World War were cast from only for the making of electros. Model casts of every character were saved in the matrix department, so the original matrices were not put at risk more often than was strictly necessary. The type would be trimmed up and finished for the copper bath prior to plating. I was told that "after 1908 all electros were made in nickel, (with a backing of copper) as it was harder and more durable."

The quiet and humble Jim Buckley worked his entire career at ATF as a "Type Clerk" for an impressive 64 years, starting at the age of 17, in 1928. He passed away, still employed part time at Elizabeth but one year before the demise of the company, in August of 1992. Jim kept these 11pt matrices on his desk for decades, and in 1986 he gave them to the last-to-be-hired ATF employee as a keepsake.
