arts and crafts bowl AW or WA in box mark

[imnideit]

Hand hammered bowl with great German secessionist-era looking mark.
There are no sterling marks but looks like coin silver because there is lots
of wear on bottom but it is not worn through to a different colored base metal, though also looks lacquered.
Thanks for all of your.

I hope someone can figure this out someday.
Thanks for all your help everyone,
