Those SPAL part numbers x-y-z mean: x - body, y - motor, z - blades. Blades A - sucking, S - blowing.
So the nearest will be VA31-A101-46S - it has paired spokes - more likely to OEM. Think i could cut the spokes and fix new inner part somehow with epoxy or whatever, if it cannot be disassembled. Rather tricky - damned spokes are misplaced! And small SPALs are rare
Well, it still can run , but still have not installed a heat barrier adhesive - will be HOT times.
