FSI Javelin Nose Cone Fit?

On the Facebook group - Rocketry Yard Sale, Buy, Sell & Trade,

Garth I. is selling an interesting OOP FSI Javelin kit.

Check out the shoulder lip overhang on the adapter and nose cone.

I wonder how many buyers left that lip on their finished models. Unless you have a lathe, it might be difficult to keep the nose cone round.

I've built a few FSI kits in the 1970s. The fit and finish of the kit parts were good, especially the centering rings. This might be a later kit release.
