Spring Barrels For Columbia AO Question

[Dave D]

I have a nice looking Columbia AO in the fancy style case, not the serpentine style. The spring barrels and ratchet are missing. Is it going to be difficult to locate the missing parts? I am under the impression that a lot of Columbia parts are interchangeable. Any advice or leads would be appreciated. I have attached a photo for reference.I'd be willing to buy a junker three spring motor if one is available.
Thanks!

Maybe a motor from a Columbia BE might work. That is a three spring motor.
