Poultry Breeders Enamel Badge

[soldon]

I've this blue enamel Poultry Breeders enamel badge, I wonder if members know if its a one off stand alone badge or part of a series. The badge is quite small 16mm diameter, the back has a pin and makers name -Lehmann & Wunderberg - Hannover. Have other members poultry breeders badges to show ?
