two truth windows

we found a lovely north facing basement window. and determined our basement is 6" sitecast concrete with a 1-3/4" x 5-3/4" pony wall, with gypsum lath and plaster, with an insulated 2x4 wall in front of it all. the really interesting part is that there is no wall sheathing or tar paper or anything, just 3/4" bevel siding over the studs.
