LNER articulated coaches

Probably a silly question, but did LNER articulated coaches have buffers on the 'in between' coach ends, or just at the outer ends of each set? Similarly, were there couplings between cars, or was the bogie also the coupling? My main source of reference is Volume II of David Jenkinson's British Railway Carriages, but having looked, I'm still not sure of the answers.
Off on a tangent, was there ever a Volume III in the carriage series, by Jenkinson, from 1953 onwards?
Thanks!

Well, now you mention it :-)

Just the outer ends.

The two coach bodies both attached to a common bogie. I believe each body had its own pivot arrangement rather than sharing a common pivot, but I could be wrong on that.

The Isinglass drawings show a single pivot.

Excellent, thanks.

Thanks. What I meant was, was there any other connection between the two coaches, other than the bogie (ignoring brake pipes etc.). I cannot imagine any further coupling would be required, as, sharing a common bogie, the two coaches would be about as physically coupled as it was possible to be.

AFAIK no other couping, apart from the pivot arrangement. That was fixed to the end of each coach, and the bogie pivoted from that.
I'm part way through building some 2mm scale Chris Higgs designed LNER artics. I don't know if Chris will be offering runs of the kits in Large Print form, he has for some of his models.

I seenm to recall hearing/seeing somewhere - but can't remember where - that David Jenkinson did intend to produce a third volume, presumably to cover (roughly) the mid 1950s to the end of the century, but it never appeared. Great pity, as just the two volumes of "Railway Carriages of the 20th Century" does leave a pretty large gap, ie the BR Standard designs, uncovered. (Although Keith Parkin's work on the Mark 1's does fill the gap very well).

Thanks David. I keep wondering why I have never seen Vol. III, and now I know. A shame - Vols I and II are excellent books, which I enjoy whenever I have a coaching query.
