Kicking around buying a Remington 513T Military Trainer. The seller claims to have the rear sight and slings but the gun does not have these parts with it at this time. Overall condition (other than the missing parts listed above) is very good to excellent with 99% of the parkerizing remaining and the wood appears to be typical of any military weapon. No splinters, cracks or major dents. Stamped " US Property" and the bolt has been inscribed by hand with the serial number. (58142) Looking for an idea of its value both as is and with the sling and sights. Any help would be appreciated.
