Here's a link to a photos of Eric Heiden riding what is described as a fill et-brazed Tom Ritchey frame vs. one of the team issue Serotta built Murray frames. First photo frame bears the MURRAY headtube decal, but the secon d clearly shows the TR Ritchey headtube decal (note the brake levers are pantographed MURRAY in second photo).
