What would I have to expect to pay for a set of original stocks for a Model 10 No Dash? If this is not the right venue for this post, please either move or delete. Thanks.

I assume you are looking for magna stocks, not Target stocks. I would say $50 to $75 for a nice set but you will only know for sure once you put them onto the gun how well they fit. Each pair were fitted and numbered to the frames for a seemless- perfect fit back then. Most will probably fit well but not perfect. Keep an eye on eBay they usually have a fairly decent number of sets at any given time but it's all about CONDITION. Hope you find what you are looking for.
