I have been scrounging for a DPM Windproof ever since I took an interest in DPM two years ago. My friend's dad has one like what I want, but that type is hard to find...many sellers carry the 95 or newer-issue ones, but not this one. I'm guessing it's the pre-95 issue, hence why it's not as common? It doesn't have the front rank slab or the "Canadian" style buttons. This is the closest I could find: (But even this one has the front rank tab)
Cheers.
