55 & 56 tool rolls like mine were in a state of confusion on what you may find in the rolls. I think the blue grease guns with the spring loaded nozzle were found in latter cars. The roll in my car has a Tecalment 3000 bent wire handle gun in it with bare metal, natural finish. Not sure if it's correct for your car or not. According to Teri Ann your car should have an Enots style gun or what was on the line at the time.
If you want to show your car in concours it's best not to display a tool roll if it's not 100% correct, you will get deductions, but no deductions if you don't show one at all.
