There is, or at least there was, an online topo to Massone. It may even be documented in the UKC logbook entry for the crag (which I think I set up). I would look it up myself but my internet connection is flaky.
If you're heading there then there is actually a large sign board up with a photo topo of all the routes so you don't even need a guide book for Massone
I'm pretty sure I have the arco guidebook back at home which I could sell to you? Ill have to check Monday, but PM me if youre interested and I'll get a price!
