That is a fine point about the eyes on "boys axes" I just recently started acquiring heads to hang and I am finding heads in the 2-2.6lb range with eyes ranges from a full sized axe eye to closer to a standard "hatchet" eye to one that is pretty short and rounded, closer to a taperd maul style eye.
Not that it is a bad thing! I just got a Norlund 2.4lb head in with full sized eye and have a HH 28" straight octagon handle that will fit it perfectly.
OP- looks like the bit needs thinning to make up for being shortened by sharpening and a reduction of the poll for balance. After measuring the eye, I bet a HH 28" octagon handle would ne very nice on there. Or maybe a CT replacement Boys axe handle.
If you have the time to tinker, fixing these axe heads up again can be very satisfying.

It does make the finding of and fitting of a handle more interesting though. As many have said before- ALWAYS measure the eye before ordering/buying a handle.
