Time was when there was a little more selection for those fans of static submarine models. No, we didn't have Revell's massive GATO and VIIC or Trumpeter's Gatos. Heck, Revell didn't re-issue its Growler until 1982. But Aurora's "Big A" line was readily available and affordable albeit a little short on the details we enjoy today. Photoetch was far in the future.
I built many of those kits, at least once. I bought a complete set (6) of the "box scale" kits for the day when I could apply what I had learned on the previous attempts.
Today, I found them.
Unsealed but complete. Including the Japanese I-19 and the Soviet Golf-class submarine. Wow. Plus a few hulls of U-boats, USS Nautilus and Skipjack which might make for good dioramas. I intend on building them using materials and techniques I've picked up from a variety of sources, including FineScale Modeler.
Some of the decals look a little yellowed, which is to be expected. I might look for aftermarket replacements.
Just wanted to share this rare find!
