Can anyone identify this labrynth/marble maze?
It looks like an older variant of the game "Labarynth".  The modern ones, made by Brio, look like this: https://www.brio.us/products/by-age/6-years-and-up/labyrinth.

The goal is to get a marble from the start (on your board, one of the corners) to the end (on your board, the crown in the middle) without it falling in any of the holes, purely by manipulating the knobs on the sides.  The knobs tilt the board on the horizontal and vertical axes, causing the marble to roll in the direction of the tilt.  If the marble falls into a hole, there should be a spot on the side of the board where it will come out so that you can start over.

Brio did at some point make a round variant, whose pattern is closer to what you have:
