Estes Photon Probe #3026 Build, Part 7, Fin Placement Differences

I don't understand why there are inconsistencies in a reissue kit. It's not a big deal, it's just curious.

The older kit has squared fin edges, shown in the upper part of the picture.
The reissue kit has rounded leading edges.




The forward "dorsal" fin positions aren't consistent. In the original kit (above) they are spaced at 3/4" and 2 1/2" up from the end of the strip.
On the reissue kit they are placed 5/8" and 2 3/8" from the back.

EDIT: Phil pointed out in a comment that in the older kit the measurements are taken from the back end of the strip. In the re-issue kit the measurements are made from the top of the taper! If the bevels are consistent, the measurements marks are actually in the same place in both kits. How did I miss that?




Here's the fins from one kit.
All parts got a coat of CWF and smooth sanding.
