Probably? likely? between 1779 and 1782 since a Vanhal divertissement for piano trio in A major was pub. around 1779 by them with plate 171, and Ernst Wilhelm Wolf's opus 3 concerto was published by them around 1782 with plate no. 532. Apparently the Danish Library itself has a date of 1783 suggested for this publication, though...-Schissel
