They are out there. In 2012 a friend of mine bought a 1957 .270 Standard Rifle from Dave Riffle Fine Guns. It was in 98-99% condition, and he paid Riffle's prices, but it was a nice rifle.
If you gather up the "usual suspects", and check them often, or possibly leave word with them about what you want, then I think you will find it.
Now, if you want a 1957 .270 AND a great deal, well, that is getting a mite specific.
