Jazz, I am no expert, but that shell is correct. Round Badge

Thank you.

So, was the wrap glued between the layers of the wood from the factory?

Yes, wrap is correct in your pic. The wood was flat when wrap glued on.

so, it becomes difficult to replace the wrap...

You can cut the wrap right where it goes into the shell and start the new wrap there. This is the standard practice.

This is the usual telltale sign that a drum has been rewrapped.

It is possible to open the joint and insert wrap all the way into the joint but the only people who would do this would be someone trying to commit fraud, usually making a fake Oyster Black Pearl Ringo Jazz Festival.

Ludwig stopped having the wrap go into the joint at some point in 1968.

Thanks for the valuable and complete answer. I did not know this Ludwig procedure, that's why I asked.

This drum is stamped 1965 but the wrap looks suspiciously new...

Can you provide some clear pictures showing the wrap?

I attach photos of the wrap, hoping they are clear.

It’s called a scarf joint
