I’m probably a month away from being able to offer it for sale as a kit.
The coupler in the photo is a stand-in. It was one of my early revisions in stainless steel. The real coupler to go with the kit will be brass, and have a working trip pin (I found it was practically impossible to uncouple two double shelf couplers without a trip pin).
The wheels are also stand-ins. They are from NWSL. They’re not bad, but kind of pricey. I’m still hoping to use Gary Raymond wheels, but we’ll see. If that avenue doesn’t open soon, I have another option I’m going to try.
