Funny thing about a manufacturers interpretation about scales. I've bought a Blitzkrieg model in 1: 48 and looked smaller than a plastic model of the same vehicle type...mmmm...I thought it was a 1:56 scale, but I was told via email it was the 1:48 version.
Now I have a 3D printer, and get pretty spot on for 1:48 scale.
BTW...just 3D printed out a Hellcat a few weeks back; will have to wait until I get home from work to make a measurement if still needed.
