I'm supprised to see both the 1/2 ton and the 1 1/2 ton fenders are the same. I have to wonder if the 1/2 ton you have got the big truck fenders somewhere along the line? I have read multiple places the big truck fenders had larger wheel openings then the 1/2 & 3/4 ton trucks had. Maybe that went away during the war years? Most trucke produced during the war would have been bigger trucks, might be such a thing as all the trucks got the same fenders after 41?

By looking at the mounting brackets, I also wonder if the big trucks angled the bottom of the fenders out a bit more to clear the bigger tires?

I would think that nose with all the chrome would have to be pre war, 39-41. Chrome was a valuable war commodity, anything produced during the war would have had mimumium chrome.

You have quite a collection going there! Do I have to be on guard of those big truck fenders I got from the scrapper guy a couple years ago? Gene
