Bluegrass Ramble -- what's the tuning?

[swampstomper]

Some time ago we had a conversation about cross-tunings. I recently started learning Bluegrass Ramble, which was WSM's very first cut recorded for Decca in 1950. Wow! Vassar, Rudy Lyle, Jimmy Martin and a "Wall of Sound" style 15 years before Phil Spector! It's a variant of Black Mountain Blues in A (not in D as is Get up John). I can't figure out the cross-tuning exactly. My best guess is:
g g / d d / a' a' / c#" e"
i.e. only one string re-tuned: the inside e" down to c#" to make an open A.
But if it's like Black Mountain, maybe the lower string are tuned up to open A:
a a / e e / a' a' / c#" e"
But then again maybe I am all wrong.

Does anyone know for sure?
Thanks!

The Bear Family box notes only says "...several pairs of strings were tuned to different notes."
Further reseach required....

I have it at home. I'll post it tomorrow. Grisman listed the tuning in Frets magazine about 20+ yrs ago.

Thanks! my ear just isn't good enough to definitively get it.

OK, bsimmers answered in another thread. For the record, Grisman says in Frets magazine that the tuning is:

g g / d' d' / a' a' / e" c#"

that is, only the outside E string is de-tuned to C# to make an open A chord.
