Years ago I found a cooey model 60 barrel in a 5 gallon pail in a shed I was renting. When we were supposed to register our firearms, I registered it as a reciever only. That made me interested in finding the parts to make it a working firearm again. Took me 10 years, but I did it. That should maybe give you a bit of an indication of how hard it is to find parts.
After changing it's classification in the registry, took it out to the range, fired about a hundred rounds of Winchester super x longrifle through it at 50 yards, and put all of them in a group of an inch and a half with open sights.
Neat rifle. Looks good in my collection too.
