What is It?

Years ago I was hiking around Leigh Creek South Australia and found an interesting object. A local said it was likely from an abandoned railway or rail car. I would appreciate if someone could please identify this “whatchamacallit”? Thank you.

I am unable to see your photos.

You will have to post them to a hosting site and then link them here. There is a good set of instructions on the General Discussion thread on the Model Railroader section of the forum.

I’m not sure if this link will work:

I use Imgur, which is a free photo hosting site.
