International Special Tools Identification Help

[cyclonejk]

Please help me identify what tools these are from my late grandfather's shop. I found these in a box some time ago and have been unable to identify what they all are, or may be used for. A few of them have numbers on them, but internet searches have left me stooped.

Some of the numbers are:
FES 111-1 (holding fixture injection pump kit)
FES 111-2 drive hub puller
FES 123-1
FES 123-3 horseshoe tool (I believe for hydro transmission)
SE 1047
SE 1047-1

I think a couple are also timing windows, but I am unsure what they are for, or any part numbers.

Thank you.

The last picture looks like a timing window for a Roosamaster pump.
