8" Ribbed Pottery Vase, Zanesville?

I've found very similar designs online attributed to Zanesville Pottery Homespun but most have raised 4-digit letters on the base (4012 for this height). Mine is plain. The color is a light muted green with brown speckling and there are about 34 ribs. Height is 8" and diameter is 3 1/2". Base is yellowy-beige.

I found these 2 on eBay that look very similar.

Any ideas?
THANKS!

 

This vase would be marked 4008, I believe, as it is 8" tall. For vases in this line the last two numbers usually indicate the height. I took a look at eBay listings for 8" Homespun vases and none that I saw were marked. All had flat unmarked bottoms or maybe just an unmarked shallow ring. The ones I saw were also the same clay color as yours. The glaze also looks spot on for Homespun (and probably my favorite glaze in that line). Were I selling it I would list it as a 4008 vase but note in the listing it is unmarked.

 

Thank you! I noticed the shorter ones were not marked, odd. I appreciate your reply!
