I learned months late that one of Burt's land speed record Indian bikes was at the NHRA museum, and galleries of photos are up around the internet

Recorded at the 2011 Grass Valley Airfest

Notice that the nose of the fairing is open, and in the Bonneville photos and film, there is no opening on the fairing of the bike Burt is racing. Some forums point out that Burt had more than one, and it may be that he had one that he kept in America for racing at Bonneville and didn't keep shipping it back to Invercargill

Photos above are from galleries you can see at
