Seems to me, Taylor uses 220 paper or emery as the last step before browning.
Carding between coats of browning, will give a shinier, smoother finish - letting it rot/rust longer & no carding will give a rougher, probably tougher finish.
This one was 30 years old last February, finished kinda rough - like me. She's had 5,000 rounds through her, probably more.
If you stand back and squint a bit, it looks GREAT!
