Catalogued in RISM as “Symphonies–G major; Manuscript copy; CH-AR Mus Ms A 102” by Anonymus. RISM 400213728
Probable
Opens like the Pleyel quartet BenP 305. RISM titles the anonymous copy G major but its incipit is encoded without the F-sharp, so the copies appear to part where it has F natural. Whether it is an arrangement of the quartet or a symphony sharing its opening is open.
