You are correct. The service entrance cable will determine the service size.
If it is aluminum, it should be #2, if it's copper #4. Anything smaller
would be a 60 amp service

What is the diameter of #2 aluminum?


#2 wire is about 0.097" diameter.

Sounds like a "main and range" panel with both "main" and "range" being
service disconnects (the range circuit will still be hot if you pull out
the "main" fuses). I believe these all had a rating of 100A. You can
use 60A fuses in both the "main" and "range" (but you may want to limit
the range to 40). (If a calculation of the proper size of the service
for the house is 100A the fuses can all be 60A.)
