The C&R market is a funny thing. First there's plenty of one item, then it dries up overnight. I think the availability of the 1911 clone you speak of is a part of C&R history. You may be able to find them here and there, at gunshows, or on GunBroker (at inflated cost), but not like you'll find CZ82s, Tokarevs, Mosins, and Mausers online through surplus dealers at the moment. I got my C&R to collect the "currently available" great deal C&R guns and rifles. If you give up on finding your 1911 at the moment, I might suggest you get a Tokarev variety. M57s are pretty popular and very available at the moment, and mechanically they are very much like a 1911. One day, they'll dry up too!
Funny thing, I remember when the Nagant revolvers were a dime a dozen. Nobody wanted them because they shoot anemic rounds, but they are just an awesome interesting gun. Folks bashed them all the time. Then when they pretty much dried up, the cost went up, and scads of people were trying to get them. Still are. Ironic.
Afterthought about cost - you can get an M57 for under $200. What a deal! In 5 years, they'll be over $300.
