Fuga a tre soggetti, Op.41 (Kalkbrenner, Friedrich Wilhelm)
Unidentified publisher, n.d.(ca.1820).
"Litografia Miniati dietro il Duomo in Firenze" literally translated means something like behind the Cathedral illuminated lithograph in Florence - could this possibly be what was meant? I don't know if this is a publisher or an inscription. Removing it from publisher information - it seems to be descriptive of where this - which may even be a manuscript copy (though a neat one)?... - was found.

This work was indeed published (near to the time of composition), as one sees @ RISM. (Mere presence of an opus number doesn't by itself establish this- consider e.g. Ferdinand Ries' symphony no.7 op.181, which (I gather) has an opus number because it was being considered for publication, but was only in fact published over a century after his death.)
