Managing production drawings through CVS

Has anyone used CVS to manage production drawings like this:
1) Engineering makes drawings using a CAD system.
The drawing files are versioned in CVS. Engineers use WinCvs
to accomplish CVS control.

2) When there is a release engineering makes a PDF file of the
drawing and adds it to a different CVS module, which is accessible
by production and service (they don't see the actual drawing 'source'
directory).

3) Production and service accesses the versioned PDF files through
some easy-to-use interface only for reading. There is never any commits
from their side.

I would like to know if such a system already exists or if I have to develop
it myself. There is a need for a down-to-earth dead simple application where
users can select from existing drawing files (PDF) and get the revision they
need to their own workstations.
The selection program should show them which revisions are available when
they select a particular file.

WinCvs is too complex and capable for this purpose and CVSWeb is also
no good.

Is there an alternative?
