As a matter of fact, EsB 365 was also considered an RCB at the time I was still putting in a steady monitoring process.
This star is extremely red and difficult to estimate vs not so nearby reference stars. A wonderful star at relative low temperatures. It requires observers with NIR vision to see its actual small variations at the true rate....

This reminds me of DY Per, another "Ruby Persei" (?), showing a similar
light curve and the carbon star spectrum. This star has been classified
as SRB: in GCVS 4.x., while many of us have been treated it as an cool
RCB star.
