Mystery Mark! Please Help

[Diget920]

I have been searching for months on an Art Deco Mask I came upon at a nearby thrift store. I thought the mask had a Goldscheider type look but the more I looked at it I realized it wasn't. I have searched and searched but the mark seems to read right side up and upside down, both ways look like a legible mark. As I have obviously googled just about everything it looks like to me, I have not come up with anything close. I'd love any help on this..maybe it's not in English? I'd be so grateful to know what I have it's driving me a bit bananas haha. Thank you in advance to anyone who helps out!

I'm pretty sure the name on it is W.K.Heinde, currently shown upside-down, it has the W K above Heinde.
