It was my Grandmother's and we think she got it in the 1950s but could be 1940s, it may have been some kind of custom build but I'm not 100% sure. The side says 'Champion Whippit' (notably, Whippit with an I not an E).
It's just been done up and come into my possession as a birthday present but can't find anything about it online so any information would be great!
Thank you!
