My '60 BN7 came with a NAPA Gold 1516 filter, and that's what I use when I replace it. I don't know the origin of the spin-on adapter on this car. Frankly, one wonders whether the world really needs all of the oil filter ones finds in the auto parts store. I also have worked quite a bit on road bikes over the years, and I remember the early days when a great many components worked together. But as time went by we had 6-speed chains, 7-speed chains, shifters with "pulls" that only worked with certain derailleurs, etc. I think this proliferation of components is done more to boost sales than from real needs. Firearms makers discovered years ago that adding new calibers boosted sale, but I digress.
