There are images somewhere on the internet (from Buchan's patent application, I believe) that show the Buchan Trap's technical drawings. There is no built in rodding point, the only access being the air vent on the 'house' side of the U-bend. Later products that fulfilled the same purpose were provided with a rodding point. You can look at a product that is currently supplied by Knowles & Sons (http://www.knowlesdrainage.co.uk/products/productDetail.asp?categoryID=12&subcategoryID=20&parentproductID=730) to see what a basic Buchan Trap looks like (they call it a 'Back Bristol Interceptor').
