Six Three Seven, Northwood
This 5 3/4 inch marigold spittoon shaped vase sold in 2021 for $40. Photo courtesy of Burns auctions.

Note the similarity to Fenton's Rib and Panel. While It's impossible to count the ribs, the ribs and spacing of the panels appear very similar and there are the same 8 ruffles on each of the shorter vases shown on my Rib and Panel page.
