Design and development
The prototype was built in Pasadena, California in 1920 by G.E. Barnhart, an engineer for the Handley Page program.{{cite journal|title=aerial age|date=5 September 1921}}
The "Wampus-Kat" was a twin engine conventional landing gear-equipped biplane with folding wings. There are ailerons on both upper and lower wings. The wooden fuselage had a small nose-mounted door that allowed access for four passengers inside and one pilot in an open cockpit above. All surfaces are fabric covered except the cabin. The main fuel tank was below the fuselage with a small gravity feeder tank.{{cite journal |title=THE BARNHART TWIN 15 " WAMPUS-KAT" |journal=Flight |date=12 January 1922 |volume=XIV No.2 |issue=681 |pages=19–21 |url=https://www.flightglobal.com/pdfarchive/view/1922/1922%20-%200019.html | archive-url = https://web.archive.org/web/20160306151818/https://www.flightglobal.com/pdfarchive/view/1922/1922%20-%200019.html | archive-date = 6 March 2016|accessdate=14 May 2022}}
