While I don't live along the NEC, I would suspect that manual switch stands along much of the route are increasingly of a very standard type. "Model 50A" and "model 51A" style switch stands are fairly universal, and can be found in yards and industrial trackage across the US. The two stands are nearly identical (for the purpose of modeling), and can feature one of two handle styles: 1) A simple weighted steel throwing lever, or 2) A more ergonomic "Back Saver" bow handle for increased leverage. Either would be appropriate in a modern setting, though new installations would typically feature the latter.
Style 1 (50A w/ traditional lever)
Style 2 (51A w/ "Back Saver" handle)
The attached drawing should prove sufficient for basic reference (for scale, I believe the target pictured measures 15.5" X 7.0" with 2" holes).
