Higher values of R may be carbon film.  Values under 10‡ are typically 
metal film.  10‡ - 100k‡ are usually metal oxide film. 

 Unless one performs a 1-hour overload test, "think" = guess. 

 For some applications, intrinsic L is important.  An example would be 
VHF/UHF parasitic suppressor service.  For suppressor service, >15nH is 
probably not good engineering practice.  Measuring intrinsic L is not 
easy.  A 50W "non-inductive" Globar typically has c. 60nH - - - but so 
does 15mm copper tubing of the same length.
