Art Deco style vase marked

This vase has an A mark on the base and there looks to be other marks too but I can't make them out.

My first thought was German?

I'm wondering if it's American. They liked that splatter glaze back then. A lot of moulded white clay pots came out of California in the 30s-50s

The shape and glaze (not the splatter) might point to Haeger Potteries but the lack of mark might rule it out.

Sometimes the US factories just used on O or USA or the 'Co' Copyright mark
