lol, I DO know this info,,,,,,,,and *I* also have more to learn on this subject, hah
let's just tackle the five shapes of the Essex angled deck ships for a start
there is the shape of the Antietam, the first angled deck carrier in the USN (she actually had two different shapes on the Port side in different time periods)
After the Antietam, there was the Oriskany, completed as the prototype for the SCB-27A straight deck ships
Then, there is the shape of the -27A +125 ships, they were modernised as 27A straight deck and then after serving awhile, got the -125 angled deck mod,,,,,,,,later, after they moved from CVA (Attack) carrier use, some of them got mods to become CVS,,,,,,,still the same basic shape as the Revell kit, though
after the 27A+125 batch, the Oriskany got the ACB-125A angled deck mod, making her another one off in shape, the most noticable being the wider hull than the "Hornet group"
3 ships were receiving the SCB-27C straight deck upgrade, and served in that config, then later received the -125 angled deck mod
then 3 other ships (as in the Renwall kit) received the -27C and -125 mods in the *same yard period*
the two batches of Angled 27C differ in that they have the starboard rear elevator and crane in the opposite order,,,,,including *moving the hole in the starboard hull that the elevator exits into the Hangar Bay through*,,,,,you don't just "glue the crane in front of or behind the elevator",,,,,the deck right in that area also changed between the two 3 ship batches
so, you end up with Angled decks as follows
Antietam (with two different landing area sponsons)
SCB-27A+125AOriskany (wider hull than the other 14)
SCB-27A+125 as the Revell kit builds (7 ships, different for CVA and CVS times)
SCB-27C+125 with elevator entrance forward
SCB-27C+125 with elevator entrance rearward
total of Five different appearances, plus the two additional variations in parentheses
