These two have eluded me in identifying either their U# or their manufacturer. They both have fully glazed pinholes. The smaller one on the left has the mold line over the top. The top of the pinhole has a bullseye set of rings. On the right, this one has a Pittsburg style glaze that almost looks airbrushed on but the glazed pinhole is all wrong.

Update! It has been suggested by two of the most knowledgable and respected collectors and researchers of porcelain that the cable on the right is a late production New Lexington which makes sense as I have learned that they did have these Pittsburg like glazes toward the end. Thanks guys!
