Chilly summed it up and Mr Garrett is very fortunate to have that bit of automotive history. I don't know what part of the world Mr G hails from, but here about the Detroit area we have occasion to see many of these kinds of "Production mementos", I have (somewhere) sheet metal ash trays from stamping plants at both Chrysler and Cadillac (the Cadillac one is even chrome plated). Miniature cast iron engine blocks make nice commemorative paper weights.
The story of production innovation in Ford's early days is an interesting story, with many colorful characters. The afore mentioned Joe Galamb is one of them that is especially associated with the metal forming end of the business. Mr. Galamb, known as "Sheet Metal Joe" or as it supposedly came across in his Hungarian accent "shit metal" was likely the guy behind that new cold rolling mill. Another key player at Ford was Charlie Sorensen a hard headed manufacturing genius known as "Cast Iron Charlie", The story goes that there was no love between these two guys. Joe was always advocating for less expensive stamped sheet metal and Charlie was the drop forge or cast iron advocate. If you are familiar with Model A's you will see that Joe eventually won out on many parts that began as castings or forgings in 1928 and ended up as heavy sheet metal stampings in 1931.
