Code 75 Diamond crossing or Switch diamond or Double slip. Suit Peco. Made from copper clad. Looks beautifully made. Overall length across diagonals 25.5cm. Sits perfectly flat unlike many Peco ones. Looks like it needs something to work the blades that flex from their mounting points and a scalpel run lightly down the centre of the sleepers to electrically isolate the opposite rails from each other.
