Default Estes Goblin Nose Cone Question

I'm currently designing a 3D model of the PNC-55AO nose cone that the Goblin uses. I have looked at a picture of the original kit (#K-55)

https://www.worthpoint.com/worthope...free-1736285235

and noticed that the nose cone in that kit has a slightly different shape from the one used in kits today. -

Has the 55AO changed over the years?

I don't think it ever was consciously changed. It was probably just from wear on the grinding surfaces, like has been discussed with the Arcas/Cherokee-D BNC-55AC nose cone. I'm sure they modeled the plastic molds after the more recent worn versions of the balsa cones.

The original Goblin had a BNC-55AO balsa nose cone....so it may well have a slightly different shape. Maybe I can get myself motivated to dig out my Goblins and we can do a comparison - original balsa nose cone, balsa repro from the Semroc Goblin repro, and the blow-molded nose cone in the current Estes version.....

That would be awesome to see a side-by-side comparison of the two! If the original is different I will take the time out do make a 3D design and post it along wit the newer version.

I think you would have to find a very early one to see much difference in profile from a late one or a PNC version.

Take a look at the K-55 kit
https://www.worthpoint.com/worthope...cket-1796976314
and the current production kit
https://brickseek.com/p/estes-gobli...del-kit/4679930

and see if you notice the difference.
