Ends set is standard Campag 1010. Note that the adjuster is turned all the way in and the hub axle is all the way forward in the axle slot of the dropout. This may have the effect of making the axle slots appear shorter than those of other 1010's.
Regarding lugs and seat binders. Just because a given machine demonstrates anomalies from a timeline it does not necessarily mean the timeline is incorrect. Imagine a storeroom filled with framebuilding bits. A builder runs across a forgotten carton or one which was covered up by other things and decides to use up those fittings even though they are the "old pattern."
