While obsessively scrutinizing some recently-acquired parts I noticed more interesting variations in the markings on some Campy parts.

I have some Campy crank bolts that are marked "Patent" and "Campagnolo" just like all the other Campy crank bolts I've ever seen, but in this case the words are stamped so that either word is upright when at the 12 o'clock position. Most Campy crank bolts the "patent" is inverted relatve to the "Campagnolo", so that both are upright at the same time. Get it? Sorry for the lame description, but I think you'll understand...

I have a single RH con dente pedal (anyone have a sinestre one?) and I noticed the markings on the steel dustcap are different from those on an old Record-with-tab road pedal. On the con dente, the lettering is set in a larger diameter.

Take this FWIW, which may be very little. Some of you might care. Of course, I thought my alloy "Patent" chanring bolt would cause a fuss, but alas.

In any case, it is clear to me that the configuration of stamped-in markings is the biggest variable in Record/NR/SR era Campy. It's doesn't seem possible to make sense of much of it. Mr. Maaslands made a good point a few weeks ago when he said that markings typically change when dies wear out and are replaced, which is fairly often it would appear. Also, the depth of markings tends to vary and because the dies are tapered (I presume) the letters can look larger when they are deeper due to fresher dies our higher stamping force.

Thats all.
