Discovered a major flaw in the kit! The rigging of the foremast shrouds doesn't make sense- they would be interfered with by the bridge deck railings. I asked in another forum (the Seaways mailing list forum). and two folks there referred me to pictures of the Bluejacket kit of the Olympia. Turns out that kit has a smaller bridge, allowing the shrouds, which are anchored at the boat deck level, to clear the bridge. One of them referred me to a national archives photo of the Olympia from the fore turret that clearly shows the Bluejacked kit is correct.
If you intend to build the Olympia and are in earliest stages, or haven't started yet, you might consider making the bridge deck slightly smaller, or moved rearward slightly. The former option would require altering the wooden deck. It looks like the real deck is as wide as the Encore/Revell kit, but shorter, so the front edge comes towards the center of the ship at a steeper angle, giving clearance for the shrouds.
