There is also this: That frame has been blued/parkerized/phosphated (can't tell from the pics)...You only do that to a finished part...

If there are machining operations left to do, then that may be some kind of engineering sample...I have two Colt auto frames that were sent to a local corporation [Carborundum] to have an experimental finishing operation done...they're in the white; but 100% machined...
