Thanks Erik!
I'm still doing some research trying to find images of the interior. I've found some with a grayish interior and others with white. I'm also wondering just how much of it will be visible.
More pictures to come this evening. I'm thinking I'll probably mask and prime the interior tonight. I haven't done any white painting since I did a British "Scimitar" in U.N. White about 15 years ago. White's not at all forgiving!
If I run into any snags along the way I'll let you know!
