Precisely! If you look at the first photos that I posted you will even see the Campagnolo envelope that the catlogs were sent out in, with postmark and all, as well as the description of the envelope contents (I picked this up from an Italian mechanic who was a close personal friend of Tullio Campagnolo who kept every single piece of documentation imaginable and dated every single piece individually.) You should also realize that there are errors in every Campagnolo catalog that I have ever seen, so I would not rely on them all too heavily. They give good guidance but are not guarantees. For example the delta brake calipers that appear in 18bis were never sold after the publication of the catalog. The same thing with Velobase; it is an invaluable aid but should not be taken as gospel as much is incomplete or mis-categorized. The ebay pedals are super cool and will reach a good price.
