This is a standard receiver from a 1956 Model 70 rifle, stamped with the serial number 389453. The tang on the receiver has been shortened - cut off slightly, otherwise the receiver is unmodified and original, without any notable damage.
NOTE: Laws governing transfer of firearms require that receivers be shipped to an FFL holder. If you do not hold an FFL or C&R license, you will need to enlist the services of an FFL to complete the transfer. If needed, we are happy to assist you in locating an FFL holder near you who can complete the transfer on your end.
