How do/did Walter Black distribute? This series is a "book club", so I'm
guessing it would be a subscription thing, right? If so, then these
leatherette and/or limited editions might have been special offers to
members, or inducements to become a member. They might have chosen their
most popular title(s) for this treatment, hence the OP's "vintage" volume in
a series of "current" mystery stories.

I've seen the leatherettes of various titles around, but never a
*numbered* limited edition...
