It looks as if because they added (known ice) after the 58 that only the
58's are certified for known ice. But if you look at the other listings,
they itemize the models not certified for known ice by placing them in a
separate line. The way it reads to me is that the B55, C-D-E55, AND the 58
are eligible for the STC.

http://www.aopa.org/pilot/bonanza/010419commentary.html says that if these
systems have dual electric pumps for redundancy, they may be eligible for
known ice certification. Flight into known-ice certification is available
when the TKS system is installed on the Commander 114B and 114TC; all of the
Cessna 210 models earlier mentioned; Aero Commander 500B, 500U, and 500S
models; Beech Baron B55, C, D, E, 55, and 58 models, and Mooney M20K, M, R,
and M20S models.

Try looking a little harder- Flight Ice in St. Louis does the
installations on all of the Barons and I think the Caravans. Some of the
installations have known ice certification.
