Help identifying vintage go cart

Contact Marshall here... I used to race Yamaha 100cc two stroke karts here... and they also run a vintage event each year. Marshall is the owner operator of this track and his father was the builder of Blackhawk Go Karts in the 50's and 60's. The kart that you have has an "extended front porch" which either says its not really that old or someone extended it at some point in time.
