Estes PF-40A?
Sorting through an old range box today, I cam across this plastic fin can and was wondering if it could be an Estes PF-40A. I'm basing that assumption on the picture from the 1964 Estes catalog, and the fact that the range box contained mostly mid-late 1960s Estes and Centuri parts/paperwork. The fin can does not seem to fit any body tube sizes I have in the stash, but according to the catalog it would fit BT-40, which I don't have any samples of.

Looks like it. You could clone a Dirty Bird III :

Looks like mine, except the version in my collection is all white.

Thanks for the info and the plan link. The red stripe is a paint job by the previous owner. Probably the same bottle of testors red that was in the box.
I am hoping to take measurements and see if I can make a 3d printable version. My current skill level is at centering rings, so it may take a while.

The plastic fin can is a fireworks item. I have several from skyrockets purchased from local fireworks stores.

I wonder if there is any melting from the motor firing between the fins?

There was some melting/charring in the fireworks version when I'd clean up the yard after the 4th of July. I never had an Estes kit, though.

I have always wanted one of these, either an original or modern version. I have BT40 and a fireworks conical nosecone that should fit. Anyone have one I could buy? |

Any fireworks store should have that fin unit.
Probably will cost you about $5 for the skyrocket.
