What means "VCOF" in "International Harvester VCOF"?

When searching picture of "international harvester vcof" on Bing images, the first 25 or 30 images are from... IMCDb. The only website to use this name?
In fact no... as the next pictures on Bing are from a website that seems to have a lot of copy of pictures taken from IMCDb. Is the site engineact.com made by someone also contributing to IMCDb?

It was an official name. The V is for V-Line (a series of V-8 engines) CO is for Cab over. I'm not sure about the F, it might be for the axle setup. It has been suggested before on our website that VCOF might be for single rear axle setup and VCO is for tandem rear axles but it might be incorrect according to these sources:

Thus, some trucks on the website might be mislabeled.

engineact.com and similar other domains are automated web crawlers. They should be avoided.

I think some cars too

I understand why these website seem so empty.

Thanks for the explanations!
