I think the biggest question is going to be about the grips. N frame diamond magna can sell for up to $200 themselves. I did a completed auction search on gb for your gun (properly listed) looks like they have been selling for between $299 and $399.If the grips are valuable I think you may have a winner. All my guns from that period are some of the finest most accurate guns I own. More knowledgble people than myself will be along for their oppinions too.
