Is it similar to Selmer's improved Albert system?
The articulated C#/G# on the Selmer works in this way: the ring for RH1 is connected directly to the C#/G# pad cup and both remain down until the C#/G# touch is pressed, so both the RH1 ring and pad cup rise under their own spring and can be closed with RH1 to make the B-C# or F#-G# trill by trilling RH1 only (while the C#/G# touch remains held down).

Oh yeah - I always get my left and right mixed up - made driving lessons interesting!
Anyway, I've gone and corrected it.
Without a picture of the Opera model I ain't really got much to go on.

C#/G# mechanism
I think your description of the Selmer mechanism does describe this instrument also, but I can't be sure. The photo in the Horniman book is not very clear.
It looks as though the RH1 ring is rigidly connected (not articulated) with the C#/G# tonehole. What I can't see is:
a) Whether the ring and tonehole are open- or closed-standing. Logic says they must be closed-standing, and maybe the RH1 ring does look just the tiniest bit different from the other four rings, which I guess are all open-standing.
b) How the C#/G# touchpiece acts.
Other features
Other features of this instrument are:
1) Three touchpieces, with rollers, for RH4: these are presumably Ab/Eb, F/C, low Eb.
2) Can't count the LH4 touchpieces.
3) Sliver keys in the same two locations as on an ordinary Boehm.
4) Can't count the RH1 side keys, but there don't look to be more than three.
5) Normal throat A key, extended throat Ab key.
6) Register key doesn't wrap around.
7) Left-hand rings are pivoted on the right (like a Boehm) not on the left (like an Oehler). But it doesn't look as though there's a linkage between the joints; again, I can't be certain.

Most likely there isn't a connection between the joints as the C#/G# mechanism will be on the lower joint, and non-Boehms don't employ the long Eb/Bb (xoo|xoo) as they have side (xxo|Bb/Eb ooo) and keyed (xx'o|ooo) Bb/Eb, plus the forked Bb in the upper register (xox|ooo) unless the LH rings also offer this as a good quality Eb in the lower register.
