The 340 was a decent rifle and chambered in the popular .30-30, it had a certain cult following, though probably less so than the Remington 788. Even if you have a complete receiver (receiver, bolt, trigger, magazine), I'd bet that you would have little chance of buying the rest of the parts needed to assemble it at a price that would be less than a complete rifle...and that's assuming that you have the expertise to headspace the barrel, fit the stock, etc., yourself. But it could be an interesting experiment...keep us informed if you go ahead with it.
