Shiranui vs Sliced Bread #2

[Nadareshiki Shiranui]

Since they're both the same moves but with different names, I'd like to know how was the first one to use the move.
I know that Marufuji debuted the move somewhere around '00 and the first time I read of Brian "(Leonardo) Spanky" Kendrick using the Sliced Bread #2 was '01 in an ECWA Tournament.
Now I really have no idea what Sliced Bread #1 is, but I'm guessing it's a Reverse Shiranui. Also, I heard that Spanky used the move that my forum handle is based on, at one of the early ROH cards. Could it be a coincidence that both wrestlers came up with the move? But...I highly doubt that Marufuji has access to watch U.S. indy wrestling tapes... but I know for a fact that in the U.S., pretty much every wrestler has access to puroresu tapes. So I'm guessing that Spanky learned the move from watching some puroresu tapes that had Marufuji in them. Does anyone know who first debuted the move in the pro-wrestling world? It's an offspring of Spike Dudley's Acid Drop/Dudley Dog where the attacker grabs their victim in Ace Crusher position and lays them out with an Ace Crusher from above.
Oh, and I heard that Sonjay Dutt of CZW/NWA TNA/MLW fame watches Toryumon tapes in his free time before...
BTW, I'd SO would like to see a dream match between Marufuji and Spanky.

The Sliced Bread#1 doesn't exist. The fact why the move is called Sliced Bread#2 is because Spanky said it's the best thing after the sliced bread (the food).

If memory serves me right, Marifuji used it first. Marifuji created it
