A neat little project corrected from an early 1970s Renwal kit. It was one of those "interior" model kits with a hinged hull that could open to reveal the inside. The flip-down half of the hull on some of these old Renwal kits were made of clear plastic. This one was Renwal kit no. 654, USS Andrew Jackson SSBN-619 in 1/200 scale. It was about two feet long.
As with Aurora, Revell, and Monogram kits, this submarine model had its share of inaccuracies, especially since the emphasis on the kit was its interior, which, itself, was quite inaccurate, of course. I left this old kit sitting in its box for years, and finally took a look at it when projects had slowed to a simmer. I remember it needed a real lot of hull contour correction forward, near the sail.
I used plenty of putty to resculpt the deck casing-to-hull contours, but I did so just a little at a time, with long periods while it just sat in its box again. Did all the scribing and parts corrections over time, but not very enthusiastically. Until I saw that it was turning out to be a pretty decent model of an SSBN.
Without hull number decals, this model could be any of nine Lafayette class boomers, but I call it Andrew Jackson because of its Renwal origin.
