To me it looks like less than 2 man days of work.
Fair comment, but there is the small matter of checking of ALL of the relative AD's, and performing a full 100 hrly inspection, even without any other inspection that may be due.
A 100 hrly will take at least two man days on a '47 machine that has absolutely no problems.
If it was an initial into country C of A inspection then in OZ that would be at least $6000.00
You may have done very well.
