It was still there. So there is a sling swivel installed in the buttstock. It is right where the bullseye should be, but is not longer there, if it ever was. Says it is a model 336, no other designation with it. Full length magazine. I even found a few very minor rust speckles at the bottom of the barrel by the action, no depth to them at all, cannot feel them. Wood is probably better than I thought. Serial number was 71 16xxxx.
