A Brief History of the Marque
Made in Austria
1923-1957 (possibly later)
Motorenfabrik Engler, Wolmersdorfer and Co
Vienna XIV, Stättermayergasse 33 (1923-1929)

Initial output was a 125cc two-stroke under the Delta marque, followed by a 170cc model under the Delta-Gnom brand.
By 1925 they had 250cc machines on offer with front and rear brakes.
JAP SV engines of 300cc and 500cc were employed in 1926, and a 500cc model was on the drawing board.
In 1927 a new 500cc machine designed by Hans Pitzek was brought to market, and the following year a 1000cc JAP SV V-twin joined it. This machine had a Burman 3-speed gearbox and 4.00x19 tyres.

BTW, I just looked at the HMW page (I had a HMW Supersport before the Lohner), and noticed my very first Moped wasn't listed as a user of the Halleiner motor. It was a small bicycle builder in my district of the city, by the name of Delta Gnom, who built a very sporty looking moped with HMW motors. I had one in silver, with a tiny standard fairing on it, and a swing fork in front.
I found an old photo of my Delta Gnom with the HMW motor. My buddy on the right is riding a HMW Supersport.
Also included was an image titled "Here I am with another buddy on old rental HMW's:" HMW-Rental-Bikes.jpg (see the gallery)
