Need Help w. Finding which keys will fit

[Papa Gleb]

Good day gents,
I have here 2 US Navy padlocks going to my collection but first I need to make keys. Any idea what key blanks would fit these 2? They look almost identical except one of them has the top a bit higher than the other.

Sorry for the upside down picture. Any idea on what blanks I need for these? thanks

I would check out SC1041R if they have four pins and C1041R if they have five.

I have a couple Waterbury US locks and they all use the Ilco 1140G/R3 blank.
The Chicago blank that GringoLocksmith mentioned looks right.

Looks like KP2 from where I sit.
