Rare Lewiston, NY arc type town postmark

The "American Stampless Cover Catalog - Vol 1" lists this cancel in the 1824-1825 arc type NY town postmarks, but without the dotted oval we see with our specimen. Without the dotted oval, the catalog value is above average at $125.00. That speaks to it's scarcity. The Lewiston oval we offer here may well be a rarity.

Partial sheet, but enough to show the date.
