  This study aims to assess the properties and classification of 55 variable
stars in Scutum, little studied since their discovery and reported in the
Information Bulletin on Variable Stars (IBVS) 985 and update. Using data from
previous studies and several astronomical databases, we performed our analysis
mainly utilizing a period analysis software and comparing the photometric
characteristics of the variables in a Colour-Absolute Magnitude Diagram. For
all stars, the variability is confirmed. We discovered new significant results
for the period and/or type of 17 variables and highlighted incorrect
cross-reference names on astronomical databases for 3 stars. This assessment
also identifies 12 cases for which the results from the ASAS-SN Catalog of
Variable Stars are systematically not consistent with the original light
curves.
