This project is like peeling back an onion with the amount of details- every time I get one layer done, I noticed another layer of things in the same pictures I've been staring at for 5 years. Its weird what you DON'T see when you are looking for something specific. I just noticed the other day that the back door has a door closer thingy at the top. After doing a quick google search for some reference, I find it is in fact called a 'door closer', and the one in question is a 'vintage' style. Its one of those every day objects we've all seen a thousand times in our life, but never focused on. Fortunately for me, a 'vintage door closer' is shaped awfully similar to a piece of plastic model kit sprue in 1/25 scale!
Then there are the fan belts: turns out that 1/25 fan belts are pretty much identical to small hair 'elastics' (discovered thanks to my two daughters!). The bad news: they only had rainbow colored ones. The good news: found a package of 500 in black at the dollar store for... one dollar. Felt a little weird buying them as they are apparently made for African-American folks' hair, so I got a coke and some peanuts to draw attention away from it.
I love the thought! I'll consider it as an added detail. But given it was supposed to be small town rural Georgia in 1980(ish), he could well be used tires; that was probably the implication. I'm also just going by what I saw on screen- never saw any of the stickers, but at least one tire on the rack was wrapped, so I might add that.
