The Revell model measures out, at the stated scale of 1/400, at 520 feet overall, which is pretty close to a T2. So a T3 would be an elongation of 30 feet at scale, or 0.90 inches. That can't be ignored.
The next step in the next ship model project; there, I've declared it, would be a T3 based Fleet Oiler in Measure 32 camouflage, just like the John Steel illustration on the box of the old San Juan Capistrano, which was always a T2 tanker.
Sorry Revell, but I own this kit box top.
I've identified the following scratch items so far:
Forecastle anchor capstan which is a half relief mold in the deck of the kit.
Walkways.
Engine room skylight.
Bridge front all decks, with camber.
It'd be nice to make two of each, in order to ammortize the effort a little.
And it relieves me to stay true to prototype on the T2 Mission Carmel, and pursue the very interesting AO build later.
One last thing- the drawings show a pronounced rake to the masts on the T2, but it's hard to see in photos. Was that rebuilt to vertical?
Next step- T3 drawings! This might take TWO more kits, but I'm good with a razor saw and BONDO!!!
