I test fitted the opening portlights some weeks ago but neglected to post any pics from inside the cabin, so here are a couple to show what they look like.
This is the starboard forward 'light in the closed position.
And here is the starboard rear 'light in its open position.
They are test fitted with plain steel screws. I will get stainless ones of the right length when I do the final installation.
A bit of a luxury item, I know. But they look really nice and were my Christmas present to PocketShip.
