What do I have here?
In my long and unsuccessful journey to build my brass Autococker, I acquired this fitting that was labeled as a “CCM Autococker neck collar” from eBay.
What the hell is this? It doesn’t fit into a standard press on neck. The only CCM that has a removable collar (that I can find) is the SS-25, but it has holes for mounting it to the body, where this only has tabs. Is that what this is, and the tabs hold the screws? That doesn’t seem secure, nor can I find another example of this anywhere. Similarly, it resembles a Phantom collar as well, but has the same issue of not having mounting holes.
The ultimate goal is to find a body that will accept my feed neck. So bonus points if anyone knows where I can find a CCM threaded body (not Angel!)
Thanks all!
