Someone on one of the heraldic forums I occasionally lurk in pointed out an on-line armorial that I hadn't seen before. It is the Heraldic Register of the Vlaamse Heraldische Raad (Flemish Heraldry Council). (This is their coat of arms here.)
The Register is a searchable one consisting of 41 pages of registrations, illustrated and with blazons (in Flemish).
The blazons have some features not always found in English armorials. Each one stipulates the pattern of the helmet (if there is one), including the color of the lining; the color of the strap by which the shield hangs from the helmet; and the tinctures of the motto scroll and the lettering on it.
I've added this site to the list of On-Line Armorials in the left-hand column of this blog under the name "Heraldic Register of the Vlaamse Heraldische Raad", or you can visit it now by clicking on this link: https://heraldiek.onroerenderfgoed.be/lijst
