Designed by H Sherman Tharpe the Duster was modified from his 1929 Sierra BLW design and claimed to be the first airplane specifically designed as a duster (overlooking the Huff-Daland ag planes).
A single place monoplane, three were built: NR10609, NR10626 and NR10627.
NR10626 was scrapped in 1945 and the others were destroyed in crashes 1937 and 1945.

Hawke Dusters was established in 1931 by Edwin R Hawke and John Cuneo in Modesto CA USA.
Built aircraft inter-wars.
After Hawke’s death in 1941, the company continued agricultural operations under this name with several new owners.
Designed by Ingenieur [Engineer] Paul Haves, and built by Automobilwerk Lauer in Halle a.d. Saale, Germany, in 1910. This was a 3-seater machine, 12m long, the main wing area was 24 sq.m. with various stabilizing surfaces, canard, etc., providing a further 15 sq.m. Weight with the pilot and two passengers was 500kg.
The HZ-5 is the last design of a series of self-built helicopters by Ing. Havertz. The prototype did fly 56 hours during flight tests circa 1966. The project was discontinued due to the age of Mr. Havertz.
The Ha-S-3, designed by Bruno Haufe, which first flew in 1971, is a development of the HA-S-2 Hobby, which had wings of shorter span (12.86 m. / 42.2 ft) and cockpit 2 in/ 5 cm narrower. It has a fixed main gear, with approach control by spoilers.

Designed by Leland Hanselman and Walter Haufe, the wood and fabric Hawk first flew in 1939, making a 9:50 hr. flight in 1940. After storage during World War II it was rebuilt and continued to fly until donated in 1969 to the Experimental Aircraft Association Museum. No spoilers.

A development of an earlier Nelson powered motor glider, the Buzzer 2’s propeller is driven through a 2:1 reduction chain, running enclosed in oil, which brings propeller rpm down to 3,000. Designed by Walter Haufe for self launching, it features a single centerline fixed wheel and small wing outrigger wheels for taxiing, with a steel tube fuselage and tail, single-spar, single-strut wood wing, and fabric cover.

Designed and built by Walter Haufe, of Neenah, Wisconsin, this single-seater high wing motor glider is powered by a 40hp Nelson H-59 four-cylinder horizontally-opposed engine mounted in the nose. The engine, when stopped for soaring flight, swings back through 80° inside its cowling so that the two-blade fixed-pitch propeller, also designed and built by Mr Haufe, is stopped in the vertical position and lies flat along the top of the cowling to minimise drag. The cooling air intakes for the cylinders are open when the engine is running but are closed when the engine is stopped. The cantilever wooden wing is of semi-elliptical planform with upturned tips, the fuselage is a fabric covered steel tube structure and the tail unit is wooden with fabric covering. Landing gear consists of a fixed monowheel and a tailskid, plus an unusual skid with small balancer wheel just behind the engine cowling to prevent the prop from touching the ground. The pilot sits under a removable cockpit canopy set into the wing leading edge. The Hawk prototype, N1051Z, made its first flight in 1962.
