Help with Pottery Pitcher

Google lens says RRP & Co but I don't see it in my one book and it's not marked. 6 5/8" tall. Thanks for your help!

 

Is this yours or another one?

Afraid the listing is not informative.

 

Not mine, but agreed - not very informative/no ID on maker.

 

Burley Winter? I’ll look for my book.
…..Update- found the book but not the pitcher though the stoneware line is very sparsely documented. I looked for my RRP book then I remembered I sold it. It’s one of the few ones that bought a few bucks.

 

I still have my RRP book but could not find your pitcher there. For what it's worth I don't think the glaze is one RRP used. I can see why AI picked RRP but that subtle bluish purple color is not one of their typical glazes. I'd guess very late 19th or very early 20th century but could be earlier. The problem is that many of those earlier catalogs didn't survive or were not well illustrated. It's a sweet little pitcher!
