"A Reanalysis of the 1944-1953 Atlantic Hurricane Seasons - The First Decade of Aircraft Reconnaissance" by Andrew Hagen at the University of Miami.

Some highlights:
1) 21 new tropical storms and hurricanes are recommended to be added to HURDAT
2) The number of major hurricanes is suggested to be significantly reduced from an
average of 3.6 to 2.7 per year during this decade (this reduction is due to the
removal of a known high bias in the winds during this era).
3) A large number of central pressure measurements have been rediscovered. If
included into HURDAT, this would increase this observations from 92 up to 301
during this decade;
4) One new US hurricane (1953 Hazel) is suggested to be added into HURDAT and
one is recommended to be removed (1953 Carol).
5) Six US hurricanes are recommended to be upgraded by a Saffir-Simpson Hurricane
Windscale Category and one US hurricane is suggested to be downgraded a category.
6) A separate study analyzed how the 10 most recent Category 5 hurricanes would
have been represented in the HURDAT of the late 1940s.
I found this most interesting from the 1944 season:
"One of the three new storms is found to have been a hurricane that occurred near
the Azores in October and made landfall in Portugal as a tropical storm. If
accepted by the NHCBTCC, this will be the only recorded tropical storm in the
entire HURDAT database from 1851-present to have ever made landfall in the
Iberian Peninsula."
Four FL landfalls (1945, 1948, 1949, and 1950) were upgraded from Cat 3 to Cat
4. Adding in the 1947 Fort Lauderdale cyclone makes five Cat-4 landfalls for FL in six
years.
The study on Category 5 hurricanes shows that casually using past records to justify
climate change not always gives an accurate picture.
