Added a couple of pictures to what I am assuming is the broke end. I may very well be wrong, open to learning why it may be that the end was not finished.
That’s a sharp observation.
I believe I see rounded edges on the rear-end. I’ve not found one of these (broken or otherwise), but it is reasonable to believe it’s complete and possibly repaired/touched up after a break.
On a side note: I can only imagine the incredible force it would take to break one of these. Puzzling.
