The early 5cm f1.4 Nikkor rims measure 45mm, as do the 13.5cm and 3.5/f2.5 Nikkors. The later 5cm f1.4 Nikkors measure 46. Thicker rims and less prone to damage.
But consider that early 135s used reversing hoods and reverse-threaded caps, the exterior dimensions may not have been an issue. Later, every lens came with the snap-ons, so, again, not an issue. It does seem a little strange that the accessory lenses kept to a narrower diameter.
