Cerveny helicons surface as a topic from time to time. Most recently represented by a posting from Slovenia:
For some reason or another these instruments also frequently are offered for sale on a second hand basis. Hence they are well represented in my gallery.
I has struck me, that they come with various ratios between bell throat and and bell flare.
The largest throats/narrowest flares are quite similar to the Cerveny Urtext tubas. the widest flares are more similar to US tubas and sousaphones.
I need to upload a few instruments of other types before uploading a new index. So hereby a sub-index of the Cerveny helicons. The most stellar representative is of the old semi-square type. I has 4 ordinary rotary valves plus a Stell-Ventil to switch between CC and BBb. CB/Getzen only were around a century late on that idea. It can be found directly via the hyper-link at the bottom of this page.

Thumbnails of three post-WWII Cerveny F helicons with 4 rotors. The throat-to-flair ratios vary:
Thumbnail of a sample of the Cerveny Urtext bell type as seen on a circa 1890 bass tuba. The sock shaped main tuning slide type can also be seen on the more recent Kaiser Bariton found a few lines above here:
Cerveny had other names put on its instruments:
Thumbnails of 4 Amati BBb helicons with 4 rotors. Today we only see these instruments with the Cerveny engraving (Yes! YM is fascinated by these monsters, even if he does not own one of them):
Thumbnails of an Amati Eb helicon with 4 rotors. Today we only see these instruments with the Cerveny engraving:
Thumbnails of an Amati Eb helicon with 3 rotors. Today we only see these instruments with the Cerveny engraving:
Thumbnails of a two Cerveny BBb helicons (4 rotors) with the Lignatone engraving used circa 1950 to 1970 on some markets:
