I can't remember where I was reading it, but apparently Albatros spinners were different depending upon what prop they were going over. Once mated, the prop and spinner were then balanced together - so you might have to do a few...
Indeed they were*, and I plan on doing at least the props that I can find in WNW plastic. That's why this one is specifically marked as AXIAL. Maybe I need to make that even clearer --
other props will not fit this spinner. The openings were clearly different depending on the prop. WNW provides a(n overly) large generic opening that fits all their props. Whether the overall shape was different -- that I honestly can't work out. It is a very elusive shape, and camera parallax does not help.
*At least according to Merrill.
