Those “ribbon” Tweeters are not stock.

That is correct. Actually only the B139 and B110 were stock. The tweeter in both designs was Audax HD100D25 IIRC. And the super tweeter Multicel ribbon. I don't recall what the high tweeter in the State of the Art was, not a T27 like in the original.
Quite coincidentally, both the builder of the State of the Art and myself purchased the speaker sets and the filter from REMO in the Netherlands. The reprint you posted here http://p10hifi.net/TLS/downloads/Atkinson-TL-QnN.pdf IS the reprint published by Remo at that time.
However, the speaker sets REMO sold in 1985 were adapted.

The scan i from the bphotocopy that came in my Blue KEF DIY binder (circa late 70s — more on that tome sometime).
The Pro9s from the same source.

Mine had Rogers Pro9s had the b139, peerless enclosed midrange and audacity tweeter mention in the article Dave posted. Sold them after I couldn’t easily move them anymore to a young engineering student about my age when I put them together, proposing to modify the tweeters to ribbons. Moved onto smaller fullrange TLs with a handful of valve/vacuum tube watts via Tannoy Six’s and B&W 706s2 (still have as my wife likes them). Missing out from of those low organ notes from Holst The Planets and the like, but the hearing is not what it used to be anyway.
