What is it, is it valuable

[bmklawt]

Hello,


I joined this forum just to ask this question, I bought what I think is a "Model A" rear axle but not being a car guy I really don't know. I bought this for a tractor project I'm working on and was planning on narrowing the axle but thought I should check and make sure I don't have something rare before I start cutting it up.
I need an old looking axle for my project, doesn't really matter what axle it is.
