Definitive way to check legacy EPS version?

i work lots of eps files every day sent me users on world. part of work, have check version of eps. must saved version 10 (i review stock logos graphicriver). know can open eps in text editor, do, method not seem reliable.

 

for example, here header info 1 file:

 

≈–”∆  p @p
c ˇˇ%!ps-adobe-3.1 epsf-3.0
%ado_dsc_encoding: windows roman
%%title: logo_original.eps
%%creator: adobe illustrator(r) 16.0
%%for: dan

 

- - - - - - etc. - - - - - -

 

i still have illustrator10 on machine (call me sentimental), , surprise, still works under macos 10.6.8.  able open above eps file no warning message, or problems whatsoever. eps 10 file. clearly, open-in-textedit method not reliable.

 

 

i have tried using "get info" on mac, works files created me.  had friend send me test file created in cs6 , saved eps v.10.

 

 

 

i found thread, , don't seem have definitive answer:

it's 2010, i'm asking now, there way definitively check legacy version?

looks version info saved system dependent meta information gets lost when transferred through internet.

 

afaik eps version determines not content of eps part of file included in ai part. when save eps version 10, ai part of file can opened in ai 10 (so open in 10 isn't eps, ai part). if save eps cs3, opened in ai cs3. if save eps 3, there no ai part.
