Please identify this Tractor

My first post here; I hope I am in the right place.
I took these photos at a recent show.
I cannot identify this tractor; I sort of think maybe a D17, but I may be miles off.
The rear tires are 14.9-28 (13-28).
I can't even determine whether it is 4- or 6-cylinder.
For comparison, it is flanked by a D19 and a C. (The D19 decal is still present on the other side)
Can anyone enlighten me as to the model and hopefully the year ?

1957 D17...  if the grille is original!

Here is another unidentified A-C and now I suspect that it also may be a D17.
Notice the industrial (backhoe) tire on the right-rear; I thought all backhoe tires were 24" ; I have never before seen a 28" backhoe tire, so this A-C may be on 24" rubber (or a 24" on the right and 28" on the left.
Is this tractor also a D17 ?  year and model? 

D-14 looks to be 26'' combine rims.

As much as I enjoy seeing them shined up, I enjoy these still working tractors. Lots of longevity helping somebody scratch out a living and I am sure some assistance from the members here to keep them that way.

So that would be an early "un-styled" WC.

The tractor just the other side of the "G" , the one with the home-made wooden tool-box, is labeled as a 1942 WC.
The description says that, because of the war, it came with steel wheels/tires and the wheels on it and this WC pictured both appear to be home-made "conversion" wheels with spokes welded into open-center rims.

Thanks for the identification.

Here is another that I have been wondering about for some time.
This one has the wheel centers dropped below the axle center.
The crease above the radiator looks as if a flat-bed truck has backed into the tractor.
I may be fooled; but, I can't imagine this small tractor handling big rolls of hay on the loader.
Check out the third-arm.
Although not pictured, there is a hay spike on the rear as well.
What model is this one ?

Thanks !
After I saw what looks like a hydraulic tank cap on the loader frame, I did a bit of reading on the 445 loader.
From what I can gather from the very limited information that I found, the 445 loader kit has it's own hydraulic pump and system, completely independent of the tractor's hydraulics --- is that correct ?
I have a completely independent Kwik-Way Loader on my 1971-72 Mitsubishi R2500.
