Good morning! I'm new here. I just bought this Hamilton Greyhound on an auction website because I loved it. I'm sure I'll like it no matter what, but I'd love to have some information about this little wagon, and I'm not finding much on the internet. For those of you with knowledge of these things, how old would you say this is? Does it look original? Do the wheels look like they've been replaced? Happy for any knowledge you can impart. Thanks!
