Restored one very similar, recently. Like yours, it needed a lot of the heel, reshaped. You still need to thin and remove some of the stabilizers, so your not honing on them. Its causing a frown, just in front of them.
Their not really meant to be Spanish points, though it is nice to shave with, they've just seen a lot of use, and time on the hones.
Scales look good, too.!
You could carefully sand the insides with a fingernail file/ emory board, or sandpaper on a Popsicle stick.
