I've never seen one for sale, but considering the prices for other rare calibers, a M70 in 7.65 would likely be priced somewhere in the stratosphere.
There used to be a dealer of rare Winchesters that advertised in the Gun List several years ago. He listed all the rare 70s including 7.65 & 9x57. Asking price even then was like $25,000. There is actually a 7.65 on display at the FN plant here in Columbia, can't remember if it was a 54 or 70 but I'd give my left nut for it...
