I have an SX-660 here:

It's all-aluminum, not aluminum shrouded plastic like some of the less expensive Simplex RDs, but not finished as nicely as the SLJ-6600. The back of the cage does say "SUPER LJ" though. Shifts very nicely, too, thank you, especially with Simplex retrofriction levers.
Whoa, hang on! I just found an SX-630 (long cage) in my Big Pile o' Derailleurs! Feast yer eyes on this:

Also all metal construction. I got this to replace the SX-410 from my Gitane tandem that broke, but haven't yet installed it.
Here's the broken SX-410. Note the aluminum covered plastic construction of this unit:
