Possibly Op.3 No.3, possibly an unpublished work?... (The incipits in RISM 450007341 do not list Op.3 No.3, which is in D major and might fit.) Described as sonata, not trio sonata (it's a quartet anyway, with a full cembalo part, not a simple continuo. I think "trio sonata" is my mistake, I should move.) If this is part of op.3, it was first published ca.1775.
