I have three 4" dia boattail that are new. These where for a project I was going to build but decided to go another direction. One is set up for a 3" motor mount and the other 2 are set for 54mm motor mounts. These come with centering rings that I had for them. They are $20 ea plus shipping or take all three for $65 shipped.

That looks like it was made from a conical nose cone.
Yes hobie1dog, they are made from a nosecone, and the tip is cut off to match either the motor tubes diameter OR the retainers diameter. The picture you posted probably uses a Giant Leap Rocketry Slimline retainer, they work nicely with boattails...and V2 tails too!

Edit: actually that might be an AeroPack retainer...but Slimlines still look better in that application.
