Dave, Mine looks very similar and I couldn't figure out how to get the forearm off either... So I did a careful tape/mask job and stripped & tru-oiled it on the gun (last weekend)
Now the reason I responded... How does your sling attach and is there a manufactuer name? Drill & tap or clipped on? I bought a used 760 for $165 with a rough stock and I refinished it, but I hate the barrel mounted front sling. H Oh.. That is the woods scope to have!
