These works:

http://imslp.org/wiki/Sonata_2_for_Thre ... _Daniel%29#

are from Grundrichtiger Unterricht der musikalischen Kunst, which seems to contain most or all of Speer's instrumental works.

Although these works are on their own pages, the Sonatas for 2 Violas and Continuo are on a page for the Grundrichtiger Unterricht, and we should probably be treating them all the same -- either all on their own pages, or all under the larger work.

Incidentally, I can't ascertain from Grove whether these were really originally bassoon or some other bass instrument. Anyone know?

These sonatas are in deed for bassons (resp. dulcians), a fingering table for these instrument are included in the "Grundrichtiger Unterricht...
These work has nearly 300 pages, not all containing sheet music. So the sonata for 2 violas should have an own page.

Thanks, I'll move it when I get a chance.

Incidentally, I saw the Grundrichtiger Unterricht on the Internet Archive, but it didn't seem to be complete - it only had something less than 200 pages.
