Carl's story takes me back to when I worked at a repair shop that got a lot of calls to unlock cars, I was amazed how many times they had a spare set of keys for just such an emergency, in the trunk or glove box or hidden under the hood, the record I remember was 5 spare keys plus the set still in the ignition all locked inside the car ! I got pretty good at not laughing til they left, and yes, there was a charge for that service.
Well I think that silver car is absolutely beautiful, better proportions than the original by far, the designer did a great job, wouldn't change a thing. The stock body has way too much greenhouse and is quite top heavy.
I have a die cast 1951 GMC Panel 1:25 scale made by the ERTL company for Snap-On Tools years ago. Proportions look decent, could probably make something out of it with some work, it was a coin bank so there is a slot in the top. There might be some grill differences between '51-'54, not really sure. You can have it you want to try making something out of it, PM me.
