I don’t think you’re going to have a problem locating this particular logo.
However if you are stuck a trick I use is to take a rubbing (as in brass rubbing) using a soft pencil and sheet of paper. You can usually scan this and then vectorize it by hand.
Also works when called on to replace the odd letter or two on a sign/van etc. that some young tyke has had a pick at, or when matching an existing sign. Take it back to the computer and have the exact size and letter style on hand for matching.
