Schweitzer Sailplane Logbook?

My ASW-19 came with a Schweitzer logbook, for whatever reason. This
logbook is almost full, and I'm looking for a new one. The Schweitzer
logbook has a very stiff, black, pebbled cover that has held up
extremely well for over 23 years. I called the SSA, and Rhonda said
that the logbook they sell has only a paper cover. I'm not eager to go
this route for a new sailplane logbook, because my paper covered SSA
pilot's logbook fell apart within 3 months!

Does anyone know where I could get another Schweitzer logbook, or a
sailplane logbook that has a durable cover like the old Schweitzer
logbook has?

Thanks in advance!
