Can you identify this knife for me?  My husband, who recently passed away, has had it for years and I never got the story from him about where he got it.  It is hard to read the stamp on the knife, but it is definitely made by Collins & Company.  The scabbard has the name Jose N. Villalobos.  There are also eight marks on the handle.  Any help would be appreciated.

Thank you,
