+1, this EDCO is from the nation that gives home to the ISO: Switzerland...of course it's made to the International Standards Organisation...standards.
BTW even tho many would think that Campagnolo being Italian would therefore follow the ISO, seems that the Campy taper is something of a compromise or hybrid...still I think it's going to fit.

On a related note, I find the Edco Competition BB and crankset a bit weird.
When installing my crankset on the BB, I do not get the same feel/resistance as I do with my other cranksets of different brands as I tighten the crank bolts. It seems like I can just keep cranking down on the crank bolts till I totally bottom down the crank arms on the spindle taper shoulders, which fortunately was able to keep myself from doing. The crank arms have stayed on securely for some years now, so maybe either the spindle tapers are too smooth, or the crankset aluminum, too soft/stretchy?? I also noted through the years, many Edco cranksets for sale at eBay that are cracked at the spindle holes, maybe a symptom of this weirdness.....
Anyone else note th8s with Edco cranksets/BBs??

Have a few bottom brackets, no crank sets.
At the bike shop long ago, Edco was one of the brands that received NO grease film, but completely dry for assembly, Campagnolo's traveling tech guys would demo the so very minimal grease film they employed, but the guy who did that with the Edco cranks regretted it.
I have one Edco BB that just developed a clunk, not looking forward to chasing down new bearings, so it goes.

The low "resistance" may be due to the fact that the tapers are chrome plated. This makes them a bit tricky to install even with ISO cranks. I don't recommend using them with campagnolo cranks. The cups and counter rings are alloy and quite soft so they require high quality tools and a lot of diligence. Also measures to prevent the alloy cup to bond eternally to the steel bb housing of the frame are called for. Overall a nice bit of bike gear but a bit over-engineered in my opinion.

The construction of the EDCO Competition allows it to be fully adjustable for a perfect chainline. The center ring on my pre-CPSC Record triple aligns with the center cog on the 5 speed freewheel. The crank arms are equidistant from the chain stays. I use a 2mm spacer on the left side so that excess threads are not exposed. Mine is French and the spindle is 121mm in length.
