A very easy kit from 1970 with only 23 parts.
There are several locations on the hull where incomplete molding is obvious & must be filled & sanded. The plastic is very soft & care must be taken not to remove too much. The hull half's do not fit together "perfectly" so sanding is required to smooth it out.
The submarine has very little detail. Also, this Skipjack release comes with a nuclear reactor that can be viewed by removing the aft dorsal hatch (pic 1, circle aft of the sail). I just had no desire to mess with it so I sealed off the hatch. A later issue of this kit (pic 3) included a "Phota-Scope" feature in place of the nuclear reactor. The kit also comes with a single periscope which I also chose to leave off based on several reference photos. Finally, the sub was delivered with a 5-bladed propeller not the 3-bladed prop in the kit.
This baby needs a little more prep & will be ready for paint.
