Horse and Jockey embossed Soda Bottle, sea glass, black amethyst ashtray chunk?

[RatherBeDigging]

Went to an area I often find whole bottles if the water is low enough. The Jockey Club Bottling Works is the coolest so far. It's definitely automatic bottle machine made but probably early days because it's clunky and aqua like the older sodas. I've seen jockey club bottles but with paper labels or pyroglaze. This clearly predates them both.
Is that black amethyst chunk an ash try?
Lot of sea glass colors too.

Could be a ashtray but might be part of a lamp

Great job on the id. Wonder what my chances are of finding the rest of it? Lol.
