sorry here are the pictures

Looks like fir to me; at least what the fir in my house (installed in late 19th/early 20th in northern NYas part of an addition to my much older house) looks like. Is it splintery - that's common with fir, and true with mine.

There are several species of fir (Douglas, white, red etc.). Some may or may not still be available by special order. Don't panic at the thought of special ordering. These days almost all real strip wood flooring is a special or almost a special, order.

You can have old wood tested and identified by a lab - the Forest Product Lab comes to mind, but I may be wrong on the name. Google for wood testing labs, or contact your SHIPO (State Historic Prreservation Office) for lead to a suitable lab.

One tactic you may consider is salvaging some rooms to acquire enough to make repairs in others and putting down something else in the salvaged rooms. You will lose a lot of material during salvage (even careful work is no guaranteed of getting it all up in re-useable condition.)

Stop trying to work with "regular" floor guys, who only have experience with new work ot tear-outs. Seek out someone who knows more about older flooring; they may be more expensive, but less frustrating for old house owners.

Good luck!

Hi,
The first two pics, it's longleaf (georgia) heart pine.
The reason they can't match it with new wood is because they didn't want to spend $16 sq.ft. for the material. Unless you can find salvaged flooring, you'll need to buy reclaimed timber. And it's high. The grain on the new pieces isn't that bad, but they would have to very carefully match the color of the antique wood. It's a time-consuming process.
The last pic is some kind of oak. Unless there's a stain on it, it looks more like red oak than white.

The first two pics really look like long-leaf heart pine, and Casey has the grain issue correct.

Any new WOOD is going to have different grain than 1924 wood, especially in the soft woods.

Any closets you can pilfer wood from in the house?

want to make a trip to SD? I've got a large quantity stored in my barn right now. We pulled it out of our house with intentions of reusing it (had to rebuild floors) but due to a lot of things - ended up not using it.

This is what came out of the dining room

And the two story section - this flooring is not the same dimension as the first stuff.

And underneath - why the floors had to be taken apart.

Your stash of room-length flooring is drool-worthy!

Once upon a time, I was research librarian for a timber products corp. In my library we had volumes with actual samples of wood grains. The actual WOOD sliced really thin, mounted as plates in these volumes. I do not remember what the title was, nor what group published it.

But perhaps a university library dealing with forest products would be able to find such a reference for you.

I think that salvaged lumber is awesome.

"Identifying Wood" R. Bruce Hoadley is about as good as you are likely to find.

It goes through a series of steps to narrow down the wood.

Some of the pines and firs cannot easily be differentiated.
