...but as I've reached the point of repainting paint wear on my restoration project, I can't recommend these thoroughly enough:

They're about a pound a tube and a lot of the colours are straight-up, no adjustment-required exact matches for paints found on Williams Sys11-era games. But I strongly recommend a flow improver to help get the proper surface during application, even though a bottle of flow improver medium is several times the costs of the paint, it is worth it.
Also on the website they have a list of conversion tables for matching up colours to other ranges of paints, including a load of the older American paint ranges - useful because you can get these Americana paints anywhere in places like Hobbycraft or Amazon, but trying to sensibly source a bottle of Apple Barrel, for example, in the UK without paying x20 the cost is a real challenge.
Just a tip for anyone else worrying about paint repair on their older games!
