Including large and small crescents, lis (large), lis (small), lis (demi), lis (3) plus the Harington ?letter? marks etc. around 80 symbols are found in the RFT series. Discounting the many straight-forward marks such as bell, triangle, star etc. still leaves us with 45 privy marks which because of their unfamiliar names and/or designs readers may need help in identifying.
