Yes, the first constellations here did not float, from memory that did not happen till the introduction of the 822A in 1958.
It was always a curiosity to me that in Finland (courtesy Markus79) constellations did not float until LONG after that time - at least 10 years, maybe longer.
If I am not mistaken it was only the non-floating versions that had the hinged base
