Parts found at an old mine, are they Model T?

[Toysx2]

I recently came across an old automobile frame and several other parts at an abandoned mine site in central Arizona. With limited knowledge and experience as far as vintage cars go, I would appreciate any input as to what I saw. I think that the frame and the majority of the parts are Ford Model T, but I am not 100% certain. I would appreciate thoughts as to the relative age of the frame and the parts. The mine was in operation from the 1920s through the 1930s. I am curious about the box near the front of the frame that seems to have a switch or valve control. I have not been able to locate any info on what that was about. Is it possible to infer whether the frame was once a car or was it a truck? The pair of axles are confusing. Their parts do not seem to belong together, is that correct? Thanks for any assistance!
