I've had a problem with the CENCO catalog files I posted on the website a couple days ago,  They won't download on Apple iPad and iPhone devices.  They download fine when I'm on my Windows 10 desktop computer.  Apparently something went wrong with the encoding of the CENCO PDF files when I scanned them.  I will have to rescan them and will post the corrected files in a couple days.

Meanwhile I added a catalog page for Eimer & Amend in the US catalog section of the website.  I uploaded one 1920 catalog and will add several more catalogs in the next few days.  This file is downloading ok on my iPhone and iPad.
