I measured the newer shade- 60mm diameter, 26mm height- measured from where the shade extends from the lens, not counting the inner threads.
The vintage shades have gone way up. The one shown, bought in the original box- at $40, considered it a very good price.
My favorite shades are the original Walz Vented lens hoods. They are getting scarce. I have several in 40mm, 40.5mm, and 46mm. I have a couple sets of the Walz filters for Canon, Sonnar, Nikkor, and even the Summitar. These used to be cheap. I have a couple boxes of filters. I have filters that just will not go into certain lenses, the threads can vary slightly- too thick, too deep, etc. Best advice- if you cannot easily screw the filter or hood into the lens, do not force it. If the threads of the filter or lens are damaged - be careful. If the filter ring is dirty, or the threads of the filter are dirty- clean them before screwing the filter in. I probably have 20 Nikkor lenses that use 43mm filters. I've looked at several today- the B&W 43mm filters fit the oldest 5cm F1.4 that I have (a Tokyo lens) to the Millennium Nikkor.
