Looks like it says:

344 126 77 D

This is on my fathers Oliver 77 Row Crop narrow front tractor.  Someone want to help me figure out what year this is?  Or am I missing some numbers off of it.  Here's a picture of the plate and of the tractor.

Yes, it's still used, and runs as good as it did new.  Got one new tire on the right side, the left one will be replaced shortly.  Right now I've got the grille in Lincoln, Ne and am going to bead blast it and repaint it.  Then it's a slow resto process...
