Some sources with very limited mention:

  OFW OK-15, OE-VAM, the 1st aircraft built in Austria after WWII. First Flight 16-7-56 designed by Otto Kauba.
  [Note: OE-VAM has been worn by at least one other aircraft]

  In Wiener Neustadt Otto Kauba started to build a motor aircraft, it was the first Austrian construction since 1937. The aircraft, the OK-15, took off on its maiden flight on 16 July 1956.

  An interesting Austrian post-war light plane, the OFW OK 15, is a two­ seater low-wing monoplane powered by a Walter Minor 4/III of 105 h.p. Span is 25 ft., length 21 ft. 4 in. and height 5 ft. 6 in. It bears a certain resemblance to the war-time Skoda SK V5.

  O.K.15. The protorype of the O.K.15, the first aeroplane designed in Austria for 20 years, has now begun its flight trials. A low-wing, side-by-side two-seater, this machine is powered by a Walter Minor III and should cruise at about 124 m.p.h. It is manufactured of metal, wood and fabric and has been built by the Austrian Aircraft Factory at Wiener Neustadt.

I think Keimel may have more information inside. Is that where the images already posted come from?

Yes steelpillow, you´re right.

Thank you.

Here is my initial translation of his text:

Österreichische Flugzeugwerke GmbH (ÖFW) [Austrian Aircraft Factory]
Kauba OK-15 (OE-VAM) 1956
The OK-15 was the first powered aircraft manufactured in an Austrian factory after the Second World War. Ing. Otto Kauba, in World War II an aircraft designer in Czechoslovakia, constructed this single-engine low-wing aircraft. Construction started in January 1956, with the first flight on 16 July 1956 (OE-VAM). Full aerobatic trainer according to airworthiness category S4K. Side-by-side seating with dual control. End of October 1956, the flight tests were completed, but it did not enter series construction because of its poor flight characteristics. Instead, the JOB-15 was built to meet the needs of the Ö.Ae.C [Österreichische Aero Club] at Oberlerchner in Carinthia.
Seats 2, Power 1 x 77 kW (105 hp) Walter "Minor" 4-III. Span 7.60 m, length 6.50 m, height 1.73 m, wing area 11.0 m^2, empty weight 505 kg, max. take-off weight 788 kg, service ceiling 4,100 m, V/max. 202 km/h, range 630 km.

The JOB-5 and JOB-15 were two light sports types used by the Austrian Aero Club. They were not related to Kauba's work, as far as I know. There is some more about them, in German, in
https://www.vereinsweb.ch/albatros/docs/VariaExtern/Reportagen/JOB%20-%20Der%20Alpen%20Klassiker.pdf
But it has at least one mistake; "die JOB 5 [war] das erste fabrikmaessig gefertigte Oesterreicische Motorflugzeug..." (the JOB 5 [was] the first factory made Austrian powered aeroplane...". This honour of course belongs to the OK-15.

Thank you my dear Steelpillow,

I want to know if there was JOB-6,JOB-7 ...... etc,or not ?.

 

[Maveric]

NO.

 

[steelpillow]

I have no real knowledge but I do not think so.

The company Oberlerchner mostly made gliders designed by Erwin Musger, see
https://www.secretprojects.co.uk/forum/index.php/topic,17923.0.html

The powered types appear to have been designed by his boss, Josef Oberlerchner.
