This is a tough one. If you do a nice job pinning on the bayonet bar and band, you still have one heck of a nice shooter .22 rifle. If you truly want to restore it you could cut it under the rear band, replace the wood, install the proper front band & stacking rod. I believe that would bring the value much closer to what an unmessed with DSM would bring, but this would cost you work and/or money and you'd have to be willing to do it. The way it is I probably wouldn't pay more than between $300 to $400 for it if I was looking for one, but that has absolutely no bearing on what someone else might pay and in the end it's worth whatever you can get for it.
