Hi,
The Cub looks in good condition in your pics.
It has the long air cleaner intake pipe, above the hood, like the 1947 - mid 1954 Cubs had. The mid 1954 Cubs, after the change at serial number 185001, had the short intake pipe above the hood.
Below is a page from the 1955 Cub owner's manual showing the pipe, and the hood and grille.

If the hood was originally white on the sides, where the names are, and the grille was originally white, they were from a later 1956 - mid 1958 Cub.
But they have said on here that new grilles from IH parts were white for some time after the Cubs with that style of white grille were made.
Look and see if it has the thicker metal Touch Control arms and rockshaft, used from serial number 185001 and above.
I guess it has the assist spring for the Fast Hitch, hard to see it in the pic, if it is the smaller size rockshaft, someone probably welded on the arm for the spring. I think you have done that before too.
Here is info from TM Tractor, they give the shaft diameters with the different bearing pics.
