I work on a lot of old martins. Here is something you may find interesting. This is an old ice cream cone heel joint that I had to redo. The artistry of the old craftsmen is fascinating.

Thank you for taking the time to post this, John.
Do you think it is stronger than a dovetail?

this is a pretty strong joint but very labor intensive. This joint did fail and I had to take it apart. The Ice cream cone was a dovetail neck joint.
The key to this , is when I put it back together . The key tenon is ramped and had to grab the heel then lock into the neck barrel. The mechanics of this neck is remarkable. The execution of the craftsman was impeccable.

Hi John,
Do you think the loose tenon was part of the original construction, or would it have been added at a later date as a repair?

that tenon is part of the system.
The tenon grabs the heel then pulls that into the neck barrel. That was the hardest part of the joint. It was surprising stiff on the dry fit

the glue on the heels miter let go and all the stress was on the key tenon. So when I did the neck reset the heel would open to the string tension. Once apart , it was allowed a week to acclimate and hhg to reassemble.
