The sextant's vernier scale reading right to left in 0 to 20 arc minutes. Note the verdigris  CONDITION: The instrument is in good condition except for some minor faults. Both of the lower legs have had  earlier repairs to their mounts. The graduated arc is slightly discolored and missing a small piece at either end that have slightly lifted. The voids created have been filed in. All the hardware is present and original to this instrument. The index and horizon mirrors are in very good condition considering their age. There are two spots of green verdigris on the vernier around the pins holding the scale and on the leg mounts.  The Bradford name on the crossbar

DATING THE INSTRUMENT:  This large sextant has advanced features which have been enumerated above.  We have never before seen them on a 19th Century wood frame sextant. The large size contradicts these advancements since improved methods of manufacturing typically result in making instruments smaller rather than larger. Baring this anachronism, we date this sextant to the 1860's and submit that it may be the one that won a prize in 1863.
