The illustrations on the 1973 brochure show this emblem, but I have never seen an actual truck of this era with this emblem. I have, however, seen several examples with the single headlights. Depending on what you are wanting to build you have options. Since the 73 brochure shows this emblem, there may have been some made this way, or if you are making a modern day custom, the sky is the limit. If you are wanting to make a period correct truck like we see in most photos, sand the emblem off and replace it with a photo-etched one. You will notice on my builds that I'm not a "rivet counter", though I respect the ones who are, but my philosophy regarding model building is: that if you are not making an exact replica of a particular vehicle, then you have freedom for variation. Remember, in the 1:1 projects, people have made all kinds of variations of vehicles. I have plans to build one myself using the old 4000 style hood, I've just got to make a grill (and finish my other projects)( L.O.L.). Keep us posted on your build, I like Western Star's!...Brian
