Sherman Klove nesting wrench set

[Papaw]

I would like to complete this set so I can sell it. OR- Sell it as is if no wrench is available to complete it.






I am not sure what size is missing, if one really is. The pin seems to be correct since it is stepped, but the wing nut is probably not. When assembled, there seems to be room for one more wrench. The sizes I have are-
7/16 x 3/8
9/16 x 1/2
11/16 x 5/8

7/8 x 13/16

1" x 15/16

Am I missing a 3/4 x ...  ?

There seems to be a lot of 25/32 wrenches out there so maybe a 3/4 x 25/32?
