About what year is that beast, anyway? Mid-to-late 1960's or is it 1970's vintage?
If I'm correct, (and there definitely is room for error on my part) it's an early 60s model. Not later than a 64 I'd believe. I was actually using reference photos from a 64 9000. I built the radiator shell by that reference, and then noticed that on Bertha the grill bezel is actually a bit wider on the sides, so I had to go back and add a bit more width to make it accurate. Not sure if the different bezel size signifies it as an earlier or later model than 64 or if the different bezel was just another customization option.
Bertha's looking a little rough! Going to be using a lot of Rust-all on that one!
I was expecting to spend tons of time on rust on this old girl. Ever since I first watched it as a kid I always thought the truck was completely brown because it was a huge rust bucket, but over the years I've come to realize that the "brown" is just a really faded, dirty maroon colour. I looked around and found that maroon was definitely offered as one of the colour options for this truck, so it'll be way less rust work. Still a fair bit on the frame and boom though.
