A lot less information is known from the 66-series than from the 38-series. I know the factory numbers from most of them, even though they are not written on the birds. I managed to collect the numbers thanks to my collected documentation. It is too bad that I can’t find information about the artists of the birds. I can’t find a lot of information about the dates and sales prices either. Briefly I can use a lot of help with those things. If there is anyone who would like to help me, please contact me.

I split the 66-series up for the clarity:

66 950 xx x
66 951 xx x.. .
66 966 xx x
66 971 xx x
66 972 xx x
66 984 xx x

Deze serie heb ik niet gemaakt; ze bestaat uit dezelfde vogels als de 66 966 serie, alleen in glanzende (unterglasur) uitvoering. Omdat ik deze vogels niet verzameld heb, bezit ik er ook geen foto’s van. Ook hier geldt mijn uitnodiging aan mensen, die me verder kunnen helpen.

Of course you can also contact me by e-mail e-mail
