Nexus sig was first, early ones has nExus on open noid. Later ones had ((nexus)) on open noid.Long lpr
Nexus dc1, next, open noid with ((nexus)) on. Different milling, long lpr
Nexus dc2 same milling as dc1 but with e2 frame with integrated beaver tail, short lpr.
Lots of people want the dc2 as it was one of the final cockers made by eclipse, it was out at the same time as the 05 ego, and to buy one you had to really want a top spec cocker rather than following the crowd and getting a 05 ego. Tbh all the nexus's when set up right fire the same! just the same as most ft1/2's ( like eelz's) a nexus in different milling, as most of these had nexus internals!
