Not quite correct. Date spacings vary on both reverses and are not positive identifiers (see screenshot of Richard's site below) and I have actually seen three spacings - narrowish and properly wide as per Richard's pictures and even narrower as per your comparison one! (Your new find is the same as Richard's first pic - narrowish with 0 just to right of bead)
The true identifier is the lack of the extra line in the shield for A# (also in Richard's screenshot) as well as the flag pole thing.
But yes, yours is indeed a no-knot 1* plus A# - well found!
It is known on circulation specimens as well as proofs, but don't yet know how rare it is, but suspect quite rare indeed!
