Lost brown wood-finish Moog Sub 37 synthesizer at Echo Park, Los Angeles.

I lost my Moog Sub 37 synthesizer while I was hanging out at Echo Park in Los Angeles. I placed it down on a bench for just a moment to grab my coffee and when I turned back, it was gone. It's brown with a wood finish, and has a distinctive twinkling sound. I'm really hoping someone saw it or has it, as it means a lot to me!
