Prompted by Ray Dobbin's frame at auction, I just discovered, scanned and now uploaded a (I think?) late 1980s or early 1990s Mercian catalog.

I also thought this is a good time to encourage you all to look at Flickr for your online photo hosting. The neat thing about Flickr is that you can upload nice huge versions of your pics. They display initially as moderate sized but by going to the "Actions" tab, and then to "View all sizes", the visitor can pull up the biggest version to study. This is a big improvement over many of the other popular photo hosting services.
