Help I.D. Front Axle

Can anyone I.D. this axle? It is 38.5" between perch centers and 48.5" kingpin centers and has 3" thick perch bosses?? I would like to use it, but it seems to be a strange size. Looks like a Ford axle to me.

 

look slike someone possibly welded on some permanent shims there by way of round lugs,....

or I'm just not in the know on this particular axle???
