273 Camshaft Identification

Hello Members. So I had, both, a 273 /180 and a 273 Commando engine. I am pretty sure I discarded the 180 H.P cam, and kept the Commando cam. To be sure, before I list the cam for sale, I would like to know what I am selling...I am sure the buyer would as well. The only marking I see on the cam is some yellow paint dabbed near the gear toward the back of the cam. Is the yellow paint an indicator, or is/are there other ways to identify the cam. Yes, next time I will mark. Thanks for the help. Appreciated.
