Actually the stretchers look like they were flat boards, maybe with a profile routed out of the top edges. The center stretcher looks like it had a bit of a scroll shape cut in it with a bandsaw. The interesting thing about this cabinet is that it looks like the legs and stretchers were built into a separate sub assembly which was then attached to the upper part of the cabinet, the legs do not run all the way from the floor to the top of the cabinet. It's too bad that so many of these highboys had the legs cut off, they never really look right afterward, even if you didn't know that they were a highboy
