Bought a few similarly graded '56 cards not too long ago, most of which are PSA 5:
6, 12, 18, 61, 113, 116, 205, 319, 336
Also have
#37 PSA 5.5
#137 PSA 4.5
#187 (Early Wynn) PSA 4
If you're interested in one, some, or all, I'd be happy to sell them for cheap (what I paid, which is about $5-9/card) + total $3.00 ship.
Best of luck in the pursuit of this gem of a set, by the way! I quit to pursue an old Caramel set, a true labor of love
