Antique Baby Push Sled

This baby push sled by Gladding Champion has both runners and wheels which are adjustable for the surface being used upon.  Since it was carefully stored, it has very little rust on the runners and some on the chrome handle (which might come off if cleaned carefully).  If memory serves me right, it was used by my Grandfather, which puts it around 1880-1890 vintage.  The blue and red paint on the seat surface is worn thin but still visible and blue snowflakes are still visible on the seat back.  Can anyone give me an idea of value on this item?
