Frederick, thanks for the review! Despite its age, I agree with you that Revell's Oriskany remains an appealing model and can provide a solid starting point for an accurate SCB-125 Essex class carrier.
That said, this is a classic kit with a number of well-known errors. The most notorious of these is probably the too-narrow hull which, though true, is sometimes overstated. The Oriskany’s beam was 101 feet (1212 inches), or 2.253 inches in 1/538 scale. Revell's Oriskany kit beam is 2.125 inches, which is less than a 1/8 inch (5.74 scale feet) too narrow, which isn't that bad on a model nearly 20 inches long. The problem is that the hangar deck bulkheads are too far inboard of the hull sides in order to accommodate the heavy solid railing and excessively wide walkways. This exaggerates the apparent narrowness of the hull and throws off the escalator on the hull side so it doesn't match up with the piece alongside the island on the flight deck above. Reducing the width of the walkways on the hangar deck sides (parts 7, 10, 18, and 20) by about 1/16 inch port and starboard to widen the hangar deck will mostly fix this. I would also recommend removing the raised planking detail from the poop deck (part 1), the main stern deck (part 2), platform deck aft (part 3), sponsons (parts 5L,12, 16, 21R, 22L) and the various island decks (41-45) as these were all unplanked steel. Oddly, Revell designers chose to depict the one deck which actually was planked, the flight deck, without any planking detail at all!
