Ok, so I saw this and I had to know! It’s almost like this one (the middle and right parts, anyway). I want to think it’s a job case, but I couldn’t find it on the extensive Alembic Press site . . . maybe for a Kelsey?
I’ve never seen a two-thirds case like this…it looks to me like someone chopped the right-most section off a full-size job case. Does the left edge look thicker than the right to you?
Here’s the link for more photos – http://www.etsy.com/listing/68253581/antique-letterpress-printer-block-drawer. The next-to-last photo shows possible holes left over from moving the drawer pull (if one side was chopped off), and the last photo makes it look possibly chopped as well. Maybe the brass corners were meant to hide that?
