Snap On KRA 429 / Roll Cab ID?

[Farmall 1066]

Went to an auction Sunday, fair amount of tools, and lots of guns & reloading stuff.
I've been wanting a KRA 429, to add on to the boxes I started out with, an old Matco bottom and Snap On top combination.

Found these gems, and bought the pair for $90.
Back of the mid box is marked 1 77, so I assume this is month/year. Can't find any markings on the bottom box.

Both are really clean, but bottom has a few dings, and some peeling paint and rust.

Any idea what model the bottom box is?

Need a better picture, but I'm thinking that the bottom is not a snap on box. Non correct badge placement.

I wondered about that too, but slides are same as the mid box, and locks are same style.
Wish I could post better pics, but resolution goes all to **** when I post them here.
Idk why, they are good when I view them?

What is the native picture file size?

Says photo is 876kb.

Try manually reducing it to ~140kb jpeg with paint's resize tool. The way it is now, the forum is automatically reducing it ~1/10 of that.

Trying this out.
