Sideplate...do you mean the parallelogram plate, or the pulley cage?

If the pulley cage:

The NR cage plates (and for that matter, Rally), though different in geometry from second-gen SR, are interchangeable. Nothing except the cage plates need to be replaced - the threaded stud on the derailer that they fit on is identical throughout, and the spring location is the same as well.

One thing - your SR's parallelogram will swing farther forward then an NR if it is a second-gen. Unless it is a first-gen SR, in which case, the cages will be of identical geometry.

If the outer (or inner) parallelogram plate:

I know that they are replaceable, but I have never done so myself. I believe the SR-style expandable pins can be re-used, but the NR squash-fit are a different story. I don't know any more then this, sorry.

Thanks for the instant reply Kurt! Sorry, I should habe been clear - just woken up the day after Night shift! I was talking about the parallelogram plate, didn't think about the swing, so that's helpful. I'll see if I can collect the bits and line them up by eye. Great collection of derailleurs by the way!

The saddle and groupset are all very similar to what is on my friend's old CIOCC,

which he leaves outside, unlocked, to rust.

Could it be an incognito CIOCC?

I really like the seatpost, btw. What make/model is it?

I was thinking along the same lines...
Here in my garage i have a frame that is amazingly similar to yours.
It's a Concorde Astore which i bought here in belgium.
It's been stripped from part for repainting and i seem to have misplaced the pictures.
What i do have are some pictures from the seller of the bike.
The lugs and braze-ons are very similar to yours, including the internal cable routing and number hanger.
Does yours have campy dropouts?
If you want i can take some pictures of my frame and take some tube-measurements.

I think some of the old concordes where in fact built by Ciöcc and brought to The Benelux, painted and sold here as Concorde.

Sorry for my english, it's not my native language.

Now for some old pics: (if they are too big just let me know)

The seatpost looks Campagnolo Chorus from 1990's?

Those windows in the lugs are almost heart shaped, but alas, no.

If you could please post some pics of the lugs, seatcluster, BB that would be great. Does your bike have Italian or British threaded BB? I didn't have time to take the fork out today to check the steerer for any stampings but tomorrow for sure I will. This bike does have campy dropouts. I too have a Concorde but it has different lug cut outs and brake bridge. Where is Belgium are you at?

the Concorde looks pretty close, but it seems to my eye that the OP's bike has "peaks" in the center of the front head lugs (both top &bottom) and the seat stay caps are different (without seeing your Concorde's I just know what they should look like and OPs look more "Benelux" to me) plus the Concorde almost definitely would have Italian BB threading.

EcoRacer

I'll try and take some pictures of the lugs and the rest of the bike.
I seem to have misplaced the ones i had taken already a few months ago.
The frame looks very much the same but with some differences.
Like the seatstay caps and the fact that concordes have italian BB Threading.
But it's the closest thing i can think of right now.

I'll upload the pictures tomorrow.
And to answer your question i live in Belgium near Leuven.

I Finally got round to taking some pictures of my similar looking frame.
Here they come:

I think the bike is a mid' 1980's Concorde Astore.

Thanks for posting those pics. Though they do look similar, the cut outs on your bike are more heart-like than mine which are more or less triangle shaped. Hopefully I'll find out some say though I plan on keeping it since it fits me very well and I like the way it rides.
