There are probably other images, but on pg. 52 of Doyles U.S. Half Tracks, Part 2 there is a 1944 shot of the dash and steering wheel. Using a magnifying glass, the horn button definitely has an Autocar logo. I'm looking for a decal, but I haven’t had any luck. Their later standard logo is not exactly the same, but it’s close enough so I just googled Autocar logo images and tried printing one. I shrunk it to 35%, about 1-1/8” wide, and it came out OK, but it needs to be clearer. I’m going to check with Staples or someone with a higher-resolution printer to see if they can print one with finer lines. If I can't find the right logo and someone to make up a sticker or decal, I would just cut the paper one out and use common glue to stick it down and then coat it over with fishing rod wrap clear resin or similar. If it comes out, I’ll post a picture of it when it’s done. Meanwhile, I'll keep looking for the right logo and someone to make up a sticker or decal.
This is the later one:
