When I was younger sometime in the mid 90's I had a push cart that had an pretend x-ray machine and all sorts of doctors stuff. I can not remember what the exact name or brand was. All the little girls use to own one. I was hoping to find one to purchase on ebay but can't remember the brand or name?
I know exactly what you're talking about! They used to show it all of the time in the Sears Wishbook when I was younger. I'll check and see if we still have an old one laying around and see what it's called.
