The same won't necessarily be true for the Mondia. As an owner of two Allegros, I've learned that the threading on Swiss bikes, of which Mondia, Allegro, and Cilo were the best known, can be almost any combination of English, French and Swiss. If a bike is late 60's/early 70's, it's likely to have a French fork and Swiss BB like your Cilo, but don't bet too much on that. You also may find French or Swiss threads combined with English stem diameters, and/or English rather than French gauge tubing. All the Swiss bikes I've seen had Campy-type threaded dropouts for a threaded derailleur upper pivot bolt, (except cheap models with a separate derailleur hanger) but it would not surprise me one bit to learn that there were Swiss models with Simplex dropouts with the unthreaded hole. Freewheel and pedal threading may also be different from what other threads might lead you to believe.
By the way, as far as I am aware "Swiss Thread" applys only to the fixed BB cup, which was the same diameter and thread pitch as French, but left-hand thread like English, rather than right-hand like French. The adjustable cup of a Swiss BB is identical to French. I've long thought that if pure logic and engineering had prevailed in setting bicycle standards, all modern bikes would use French threading with a Swiss adjustable cup. French thread, after all, was entirely metric, which since the early 50's standards organizations had been trying to make universal, and the Swiss left-hand fixed cup corrected the tendency of French cups to work loose, while retaining metric dimensions. But the market share of Swiss, and ultimately even French manufacturers, proved to be too small, and the Japanese combination of sound engineering, efficient manufacturing and astute marketing too powerful. As a result we now have ISO standards that basically sanctify the English thread standards that as a small schoolboy in the 50's I was being taught were obsolete and slated for extinction. Go figure.
