What was the date that this AC&F proprietary roof was first applied

of cars?

Thanks for your reply. Don't go out of your way to answer this - just
wondered whether you knew the answer without further research!

A.T.,
The earliest build date was March 1948, WLE 23500-23749. Reading's
earliest box cars (107500-107999) with this roof were built 8-48
followed by M-K-T cars in 12-48 (97001-97300). All of these cars had
ACF proprietary corrugated ends as well as the roofs.
