Truth casement window operator

I need to replace the right and left operators.  Pictures are of the right one when looking outside.  I bought some small right angle screwdrivers and my hope is I can take the screws out without taking off the sash which has been painted over times.  I just want to double check I am getting the right one because in the pictures I find on your site, the universal replacement looks slightly different than mine.  Mainly the mechanism that's near the "Truth" stamp in the metal.  Thank you!  I appreciate your help!
