Hi,
Engraved heraldic colors (tinctures) are depicted with lines in various directions and dots.
Lower left shield here is called ``azure or bend`` (blue, ``or`` - gold In French).
There was a famous dispute in late 14th century regarding this heraldic shield.
http://www.medievalists.net/2009/05/the ... 1385-1391/More heraldic symbols and shields were added through marriages and acquired peerage.
Birds ``close`` are on gold, buckles and lion? on blue (azure).
Lion, as depicted here, is questionable, though. Cannot tell if ``lion passant`` at all, right fore paw is not raised.
That`s all I can tell, hopefully something to start with.
Regards
