Paul DeWitt writes, "Is that an Ampico roll in the [Duo-Art] drawer?"

Paul, if you look inside the back cover of the same magazine, you will
see that AMICA offers several Ampico and Duo-Art roll leaders for sale.
The most common Ampico leader was also used on some Duo-Art rolls after
the merger of the two corporations.  So it is probably a late Duo-Art
roll in the spoolbox.
