I recently picked up a Kodak Brownie Holiday Flash. As I love to do portraiture, I later purchased on eBay the 6-A Close Up Attachment. I thought I got the right one, but apparently not. The manual refers to this filter, but does not indicate what size, or how it mounts. There is a quasi threaded fitting on the inside plastic piece that houses the lens of the camera. The filter I got has 4 sets of pairs of metal tabs. Apparently, these filters were offered in different sizes. This one is 28.5mm in diameter. Needless to say, the filter just swims over the fitting- there is no way to mount it. Does anyone happen to know the right size 6-A that I need to fit this model camera?
PS- I have attached images of this situation.
