Anything that is added on after the frame is constructed. Claud Butlers, Paris, Rensch, Cottinghams and Hetchins all used this form of bilaminated construction on some of their models. In the case of the Paris in the picture this was a fillet brazed machine or some call it welded. The bilaminates were cut from flat sheet metal formed around the tubes and silver soldered into place after the frame was constructed. This goes for all the other frames. The Claud Butler Avant Coureur and Olympic Sprint are good examples of bilaminated construction from this maker. Hetchins fork extensions and the ornate lug tangs on the MO and MB are indeed bilaminates as are the ornate personalized initial plates so common on Hetchins. No you can't call braze-ons bilaminates and yes some of the modern makers use aircraft glue (Araldite) to affix these add ons. Strictly not kosher but looks the same under layers of pristine enamel. Hope this clarifies things.

Best wishes and be lucky. Michael Butler Huntingdon UK.
