Can you help me ID this dish ?

Please excuse my almost total ignorance about glassware. I happened across this and thought it worthy of research.
1. Is it cut or pressed glass ? (There - ignorance exposed)
2. Age ?
3. Maker ?
4. Pattern name ?
Photo 1 - overhead
Photo 2 - closer
Photo 3 - arbitrarily decided 12 o'clock position.
Photo 4 - opposite side to photo 1
Photo 5 - a detail
Photo6 - bottom
Photo 7 - bottom

 

hit create too soon -

 

Oh boy - forgot dimensions - diameter - 6 1/4" across top (16cm).
Height - 1.5" (3.8cm).

 

How sharp (or dull) do the places where it would be cut feel to your fingers? What about the "points" on the edge?

 

I'm having a difficult time tonight. I got kicked off without realizing it.
Lost my reply. So - the little dots on the squares feel like the surface of a fine wood rasp without the "cutting power" if that makes sense. Nothing feels like raw glass or the edge of broken glass. I can't detect a seam. The only edginess I feel is on the edges of the triangular rim points, on the surfaces faces the interior of the dish. I'll try a few more photos.

For what little it ads, the only mold seam (to be found or felt) is around the edge. There would be no other seams sin this shape. Also, the gray areas in the last two images were cut with a grinding wheel to give a bit more character to the plate. This technique wasn't used until the last third of the 20th century, generally, though there might have been some use of it earlier. I'd date your piece accordingly, last 1/3 20th century.

 

Thanks. It's a challenge.

 

Thanks.
I'm still curious as to possible Maker or if the design has a name.
I found a mark on the rim that may be a mold mark or may be a scratch - my fingernail catches on it. The alignment makes me suspicious.
