Some info on these helicopters are supposed to be available in this publication: https://www.antikvariat.net/sv/rud2...ts-forsyningskommando-i-anledning-av-det-i-ar

Does anybody has it in an electronic form?

About X-2 you can also read in a Samhold (Gjøvik) newspaper from 9th April 1960.

This is picture from this publication mentioned by me earlier (at least it is declared as source on this wikipedia wrap: https://lokalhistoriewiki.no/wiki/Fil:Helikopter_PK_X2.jpeg).

Actually I am surprised how little data and pictures surfaced on these helicopters to this date. The X-2 development process took at least 6 or 7 years up to the moment it was terminated.

Thank you my dear Persil,

and here is another picture to it.

That top-mounted engine reminds us of similar Polish helicopters.
Was there any Polish influence on this Norwegian helicopter?

I don't think so. But it is a bit similar in look to Mil's V-8 and Sikorsky S-62
