My guess is that you have a European-delivery Duetto. The bucket shown in your OKP photo looks like a US-delivery style. The difference is that European cars had separate reflectors and bulbs, so their buckets had what you call the "cap and clip" that allowed the bulb to be changed without disturbing the reflector (and headlight cover). US cars came with sealed-beam headlights, so when a filament burned out, you had to remove the bulb-reflector unit it from the front - rear access wasn't needed.
750/101guy's suggestion of contacting OKP is good - being based in Europe, they are likely to have this style of bucket, while US-based sources are less likely to have them.
Note that a US-style bucket - even one from a squaretail spider - will function just fine, but will require more fiddling every decade-or-so when you need to change a headlight bulb.
