Hi, Slightly concerned about this one as, but for the front dumbirons, it could be an American Flanders. Subsequent research of humpy bonnets suggests it is a French Brouhot but I have not been able to find any other photo of a Brouhot with that type of bonnet, or downfacing dumbirons. The Brouhot bonnets were normally simply wavy rather than edged, and dumbirons just normally curved. As no picture, cannot advise date, but the Flanders would have been cca1910. Would love to see any other photos of a Brouhot with those features for my system! Regards Vintman
