Latest find from eBay: The S/N is 205576, the cap jewels on both the pallet and escape wheel along with the upper barrel jewel makes this a 22 jewel movement. It is marked "Maiden Lane" and "adjusted" but does NOT have the jewel count. All plate numbers match, along with the hand scratched S/N on the underside of the balance arms. Kent Singer and I have S/N 205575 and 205586 in our database, both are 17 jewel Maiden Lane movements. This is the only 22 jewel Seth Thomas we have recorded. It is pendant set, single roller, with diamond end stones, gold jewel settings and gold balance screws. Anybody have any additional information or comments to share?
