The yellow film caps look original, that's good because they last forever. The coils look like the originals, too, however it appears that the iron core has been moved judging by the glue to the left of the speaker terminals. The little green NPN looks different, I think they were silver originally, they are really the only crossover part known to age. So yeah, it looks "refurbished".

Where's the 600uf cap for the woofers. I think you may be missing some other caps as well. Check the schematic here. http://www.infinity-classics.de/models/Reference-series-1+b-2-10+A+B-1981-86/index-Reference.htm
Should be 4 values of caps and 5 coils...is there more stuff above where we can't see?

You bring up a hell of a point. I'll check again today and see if I may have missed some components.

Jim's right. Somewhere we are not seeing the big woofer series cap. Probably was where that glue is. The red wire in the shape of a rainbow, on top of the curly one that looks like a pig's tail, is the woofer + wire. Maybe the cap just fell out of the glue and is attached on that red wire a few inches away. All other components look original. Looks like there's even a bit of corrosion (the white powdery stuff) on the outside cover of the midrange pot. Very common.
If the woofer series cap isn't in there, don't panic; the speakers operate just fine without it. There are scientific reasons why that cap is there, none of which are 100% necessary for the speakers to run without.
