Winchester M1894 Dart Gun (Non-Functional, Needs Repair)

I bought this shell ejecting foam dart blaster, and took it apart to try and clear a Jam. Sadly, I do not know how to put it back together. Selling for $50, because it cost me ~$150 online. Might be good for cosplay, or if youre good at fixing things you might be able to get it working again. I still have all the internal parts.
