Hi ! I have some years ago a rare Ditmar donut hanging lantern. We found it in the loft of the church . I didn't see this model number in catalogs, and i dont know when it's made. If you can help, please write. This lantern beautiful for me, but unfortunatelly, i dont have a proper place for this.
That looks more like model 423. That would make it a 800cp kerosene do-nut the same as model 421 but without a built in pump. ::Neil::
@Roy77 Is this the same one as on the thread you posted back in July 28, 2014? Ditmar Maxim 423 from 1937?
