I am just surprised that lowes and hd have a category called "basement windows", and the one I linked to was not in it. I suppose there could be something different about the flanges, since the exterior ones are going to meet up with mortar. It may be of note that I will need to replace the window frame and will not be sliding a replacement window into an existing frame, which is just a screw and caulking operation. I will have to build some kind of frame to attach this into, trim it, and fill with mortar.

Below is a picture of the existing window from the inside. Tomorrow I will get a picture of the exterior if that would help.

You are correct about the construction, they nailed the window frame to the underside of the sill ledger and then used granite tailings to shim the sides of the frame to the large granite blocks that make up the opening. These shims were just mortared in place. You can see this on the first attached picture. They used nicely dressed stones under the window, but nothing like an actual sill. These stones don't run all the way the full width of the foundation, so on the inside, they just made a rubble pile from what ever was handy and covered it with mortar.

I was going to pull all of this out and make a new window frame out of 2x6 or 2x8 pressure treated squared off on the table saw. I was going to make the verticals almost twice as long as they are now and run them down through the rubble pile to the large granite blocks lower down and then bury the bottom of the verticals in concrete. I'm a bit unsure how to trim the outside. You can see in the second picture that the old mortar was just run up to the wood on the old window frame. I could wrap the pressure treated and run the mortar up to the flashing, or I could run the mortar up to the pressure treated and then trim the outside with azak.

Since this is a replacement window, would run the trim over a bit as a stop? Would I be overdoing it with 2x stock instead of just using 1x?

I think I more or less know what to do, but it is always more complicated when you get down to it. Of course, the current construction could hardly be more crude and has held up for more than 120 years.
