Jake,
I was surprised to see this too and that's why I question it if only on the basis of what seems logical. I have now found some posts (http://www.seaways.com/subarc99/constitution.htm) that say that the ports were there but were not hinged (except for the two closest the bow):
"The gun deck gun port lids were NOT hinged until about the
American Civil War but, prior to that time, were completely removed and
sent below when exercising the gun deck guns -- no gun port lids were
provided in the spar deck, ever. The gun deck gun port lids were split
in half horizontally in 1804 but were still NOT hinged, with some minor
exceptions to this up forward."
This is from a Ray Morton who apparently did a practicum on building the Constitution. If I can find some confirmation of this I might just build with the lids off (save for the hinged two at the bow) as if she were going into action. I just wish that people would cite their sources for assertions like this. Maybe I should just relax and build the model...
Thanks for your input. Appreciated as always. Loved your account of shopping at Walmart.
Bob
