These are P1853 cavalry SWORDS in their official title. In British terms, a sabre (saber) is more curved. The US term for all cavalry swords is 'saber'.
(correct me if I am wrong) They were for issue to 'other Ranks' as officers bought their own. Like the Enfield P1853, they were used to effect in the Crimean War. These are 'private purchase' and will bear no acceptance marks. It appears that Georgia put in an order for a number of arms in 1861 without goung through central government. The 'G' was prpbably stamped on before loading for export, as were the Enfields, and appear to have been shipped in boxes of 25.
Tim Prince of College Hill Arsenal (

Given the fuss about Georgian Enfields in these early shipments, it seems likely that these were the swords landed in 1862. Equally, since the term 'swords' was used, it will have been taken directly from the manufacturer's invoice and ships' cargo lists rather than off-loaded accounting lists
