Plastic train track (Batchwood/ New Greens AL3)

Good amount of well used plastic train track. It's unbranded so uncompatable with anything currently on the market as far as I'm aware. It could do with a quick run through the dishwasher/ washing machine as its a bit dusty. Some of the junction pieces only have indents (see second photo) which messes up the joins on a loop. My son is too much of a pedant to put up with that anymore but hopefully it'll bring joy to a child with lower expectations!
