These slides are mounted in thick plastic which is interesting too.
Being nosey I zoomed in on the brake wheel to read the lettering.
Seems Miner is still around : https://www.minerent.com/index.php but be careful they have all sorts on interesting features there like the boxcar rotate : https://www.minerent.com/products/interactive/interactive.html and you will spend too much time playing around there.
