https://quasr.flatironinstitute.org/model/104183 and https://quasr.flatironinstitute.org/model/0104183 both point to the same device model, and both URLs work. However, it's kind of annoying that the non-canonical form still shows up in the address bar.
Consider whether it'd be difficult to replace the location with the canonical URL when the non-canonical (missing leading 0s) one is used.
