I never actually used that 28T ring but I probably got it when I bought a middle/40-something Cycloid ring that I used for a while as part of single-ring setup with an early-90's Shimano LX crankset, which was 110 BCD with, what, 74 for the granny?
I just measured it, and it's about 44mm, which makes it 74 BCD.
