Henschel Hs 297 Fohn?

[Vasco Da Gama]

Pictured is what I think is a Henschel 297 Fohn rocket of WW2 vintage. I understand that these were used both in a ground launched Flak mounting, Beercrate Flak, and were a potential option to arm the rocket fighter Bachem Ba349 Natter with 24 being mounted in the nose. The overall length of this example is approximately 285mm including the fitted ZZ505 Fuze, the main body is 163mm long. I am assuming that from the design the main body could vary in length with the same nose and exhaust nozzle being fitted. Any information on this projectile would be of interest and potential confirmation of my ID and use in the Natter of this size projectile would be really useful. Picture alongside a 3.7cm Flak round for comparison.

Superb. I was going to ask what this one was I'm in the process of cleaning up. Totally empty and quite lightweight. Yes, more info would be great.

Scroll down and it looks like they're fitted in one of the planes.

Yep, this appears to be the true story about the 7,3cm and the Ba-349 Natter.

The rocket in the first post obviously is the "Foehn" rocket, but... I have absolutely no idea, why is the rocket usually attributed to Henschel and designated as the Hs 297. :/ The only designation actually used by the Germans, I've encountered, is 7,3 cm R-Spgr (with or without the dash), while the codename Foehn apparently applies to a whole family of AA salvo launchers, not the rockets.
The original fuse of the rocket was RAZ 51 (Raketenaufschlagzuender 51), clearly derived from 20 mm flak fuses armed by rotation, e.g. Kpf.Z. 45.
