Charles Burdick's design had developed significantly from the original WalkupAirbrush which he had initially copied. Above we see the design presented at the 1893 show. To our right is the updated patent for the 1896 Production model which can be seen partially dismantled below. Note that Burdick is not named as the inventor as by this time he had left for Great Britain. The instrument would cost $30 for the handpiece or $43 to include the tank and pump.
