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...

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.

Hey ,
Raoul again .
Two thoughts ( again ) :
**1.)
I'm the proud owner of a Schwinn Deluxe Paramount P15 Touring 15-speed . Interestingly it's a 1970 . Makes it the model & year chosen to be "The Diamond Jubilee Schwinn" . To the point - it's only very slightly used . All stock , even the tubes & tape .
Serial # H7038 , the 38th frame made in the Paramount shop in August of 1970 .
Pedals are Pista "con dente" . Campagnolo made them road , toothy-track , & smooth-track at that time ( Hey Chuck , was there ever a toothy-road pedal ? ) . My guess why toothy track on this machine - to work better with casual shoes .
Compared with 1972 Frejus Legnano Professional Record Super Corsa . I know this is a 1972 because not only did the shop tell me it was fresh from Italy , the paint was still uncured & somewhat soft ! And I know those are the original pedals , road , with loops .
So I compared pedal dust caps . Now , I noticed when I first got the 1970 Paramount that the pedal dust caps were subtly different somehow . We all know steel pedal caps have inset letters ( intaglio ) , and plastic pedal caps have raised letters ( cameo ) . Have you noticed that the "dome" on the plastic caps is a smaller diameter than the entire cap itself ? That leaves a small transition area near the edge , where the slope changes . Once you've noticed , you'll always spot it right away . My 1970 steel pedal caps have the same dome-with-changing-slope as the later plastic caps , and an inner diameter of the lettering-circle of 4mm . My 1972 steel pedal caps have a dome that runs all the way out to just about the edge of the cap - no transition! , and an inner diameter of the lettering-circle of 6mm .
By the way , we could say that the edges of the pedal dust caps are toothed ( "con dente" indeed ) .
But , numismatically speaking , that is a "reeded" edge .
Cool huh ?
**2.)
I'm sure that this has always been true . But , I first read about it with the introduction of the then-brand-new Mavic Open 4 CD rims for wired-on "clincher" tires ( like maybe 1987 ? ) .
If you get a rim that was made using brand-new-fresh-dies , the clearances on the extrusion machines were tighter , the rim has thinner walls , the rim is lighter in weight .
If you get a rim made using a tired-out-old-die , just before it was replaced , the clearances were larger , the rim has thicker walls , the rim is heavier in weight ( and surely stronger as well ) .
How much difference can it possibly make ?
Well , ever seen a bicycle with an aluminum seat binder bolt instead of steel ?
I sure do like my original 1972 Hi-E hollow aluminum tubing water bottle cage .
And yes , I do drill out all of my water bottles , thank you very much .
Happy Trails ,
