several of the "B&H/1914"s (if not so marked in their score- have not seen the scores) can be confirmed at HMB 1914, page 182 (first page of September 1914) where one does see "Brian, Havergal. Kompositionen f. Orch. Leipzig. Breitkopf & Härtel." followed by the list (compressing) Doctor Merryheart, English Suite 1, Fantastic Var. on an Old Rhyme, Festal Dance and In memoriam (score of each costing 10 n. :) - not sure what that stands for; I assume that the price is what's at the end of lines in HMB listings, but may be mistaken...) In 1914 I know more scores proportionally carried copyright notices than a few decades previously, but still not uniformly all of them (or even enough of them, really, so HMB still a useful resource. Anyhow, I know the fact that these scores were published at these times is available other places but thought I'd give the confirming stuffs.) Eric 23:32, 24 June 2011 (UTC)
BTW it's possible that some of them, esp. Dr. Merryheart and In Memoriam, were first published ca 1913, and the bundle first published 1914. So yes, going to seek out their individual plate nos. (They may have a different plate no. when published as a set- this is precedented, have seen such cases quite recently.)

As to In Memoriam, in the Library of Congress' "Catalogue of Copyright Entries" (1914, p.8063), In Memoriam is given as "IN MEMORIAM: tone poem by Havergal Brian; Full score for orchestra, Leipzig, Breitkopf & Härtel. [8072. "© Nov. 10, 1913; 1 c. April 23, 1914 ; E 333675 ; Havergal Brian, London." Not sure what to make of that but it suggests a copyright of 1913 - don't know what the April 23, 1914 part means though. (Another source gives a premiere report in the early 1920s. Hrm!) Will keep looking...) Eric 04:19, 25 June 2011 (UTC)
