Langgaard, Rued (1893–1952)

Symphony Nr. 1 "Klippepastoraler" (published by Samfundet)
Symphonies Nrs. 1-16
Any other works for solo piano

the majority of Langgaard's works, including (as far as i'm aware) all of the symphonies, were not published until Edition S started issuing them in in 1998. these editions would be unlikely to be public domain in any country. as for the manuscripts, they are mainly held in the royal danish national library in copenhagen, and have presumably not been made freely available in digitised form because in denmark they do not enter the public domain until 2023. Cheap Imitation 03:50, 13 September 2013 (EDT)

not all the symphonies. Edition Samfundet (t. Dansk Musik) ( = Edition-S? ) published symphony no.6 (1919) way back in 1946 (Edition Dania imprint?) (and others of his works earlier still.) - E.S. (and sym. 4 was published in 1973 by Dan Fog. Sym. 7 may have been published in 1927, not sure...) Ah! I see. Interesting... the 7th symphony, 1926 version, was considered missing until a score published by the composer at his own expense (I assume sometime ca.1926, but maybe not- between 1926 and 1952, not 1998, anyhow) was discovered , which formed the basis for the recording in a review of which I found that information... (and ah, again: HMB lists - Monatsbericht (1927), p.125- "Symfoni No.7 Fdur f. Orch." by Langgaard, published by Hansen.)

Also, unless their recent publication (1998) or something else is a consideration, well, it is now 10 years later (i.e. 2023) and so some of the works you mention above should be PD-CA/EU now. -ES

Le Sueur's?

Cousin of the above composer; resident in London.

"Lesson for the Harpsichord" (1712)

This last piece is identical with the Quintet in B minor (Loeillet, John). The orginal scoring ist for 2 voice flutes, 2 transverse flutes, and basso continuo. Voice flutes are recorders in D, which transpose a minor third down (because the standard ist the alto recorder in F). Some modern publishers transpose the piece to D minor to make it playable for normal recorders.

Did die in 1882- obituary notices here and here. (Also? J.F. Meilhan unless this is a different composer. P.-F. Meilhan does seem to be a different composer.)

Noli me tangere, op. 87 - movements 3 and 4
Violin Sonata, Op.10 in E (pub. Apostol, 1909.) I think NYPL has this (in their research collection if not nec. in their online catalog. UCLA also has.)
if the 4th quartet op.62 (no.1?) (1910) ), string trio op.133 (1927) or other later chamber works e.g. the wind trio op.154 are available in PD-CA versions, those too, but I doubt it- they all seem to have been first published commercially 1964 and on, from what I can tell. (ok, we now have some of them though as manuscripts.)
Addendum: MSS of symphonies 1-5. All date from before 1923. (poss. concern still)

Große Sonate zu vier Händen, Op. 10 (Berlin, Stern & Co., 1846?)

Mewes, Georg (1887–1932)

VIAF gives 1790-1870 for the composer Georg Mewes but since his compositions only started being published in 1895, and since his son Heinz started renewing his (Georg[e] Mewes, composer of the much-arranged song "Lena", published 1931) music only(?) in 1933 or so according to the Catalog of Copyright Entries maintained by LoC, this seems mighty unlikely.
