thank you iab for these two links.

both are new to me; much appreciated!

--------------------

thank you three alarmer for the information regarding the bb. odd that it is a mixed set with tullio bb fittings and carousel company chainset.

sounds like you are well on top of manubari matters.

dating is curious. iirc the campag record chainset and front mech launched right about the same time in 1959-60. the pros would typically get new components a bit before they were available to the general public so this can slightly complicate the timelines.

since machine is clearly a first quality model it seems odd to be fitted with a gran sport front mech and a rear mech which did not launch until 1963.

not challenging anyone's dating; just curious to understand more/better.

thank you again.
