I have noticed during Eddy's Faema years, the head tube does seem slightly shorter than on his Molteni, or even later Fiat and C&A bikes. This could be as a result of a larger frame, or maybe a higher bracket height on his later frames........I believe he used 177.7 cranks......but maybe not in 68/69?
I believe it was me who first questioned the authenticity of the restored bike as in the photo of Alberto Masi......since then, thanks to the response from several on this list, I have learnt something new....that Merckx did ride a frame with the slotted chainstays.......and it does appear in a photo I've just uploaded to my flick site that he also used a steel Cinelli stem during his Faema years!
Interesting stuff.....well it is if your a Merckx fan as I am.......
