Hi Jan. Heres the link to the sweedish site Boije Collection. Here You can find the work by Molino. In the sheet it says below every sonata in the opus number, 1795. I gues its the year of the printing  http://www.muslib.se/ebibliotek/boije/indexeng.htm.

I see that Your a historian. I myself is very fond of history, especially the 19th century, thats why I play this historical instrument. If You havnt seen the video with my duo in this site You should check it out under videos. We're called Duo Historico - guess why ;-)
