Hello I am looking for some detailed pictures of mit to late 14th cent. scabbard fittings. Unfortunately I don´t have too many detailed sources, most are very crude in paintings. Some sources would be fantastic.

Not only surviving pieces are of interest, but also all kinds of artwork.

Felix,
This old thread of yours has pics from the latter half of the 14th century: http://www.myArmoury.com/talk/viewtopic.php?t=11077

It also links to this website with lots of brasses and effigies: http://www.themcs.org/armour/14th%20century%20armour.htm

You could also try http://gothiceye.com/ . Or our article on brasses: http://www.myArmoury.com/feature_brasses.html

Or you could pick up one of any number of books on brasses and effigies. You'll probably get more detail with brasses and effigies than in some period art.
