Tom, it appears you are missing several pieces to your unit based on the design of mine and/or the ones I have seen that are like yours. BJ Miller with Ron's Machine in Shandon, Ohio (
https://www.ronsmachineshop.net/Home.html ) has a couple of units similar to yours. I would reach out to him regarding info about them. I have uploaded 4 pix. The first picture is of my Storm Vulcan Model 24. The next 3 photos are of BJ's units so you can see what is missing on yours.
