I've seen where there is a few No 1's going to be at auction close to me. What would be a good stopping point (price wise) for them if they are in good shape? One is a .223 and can't remember what the other two are chambered.
All depends on the specifics for each and how much you want them. The best stopping point is when the price is more than what YOU, yourself decide it's not worth more to YOU. Generally, I'll see them in the $750-850 range depending on which variation and chambering and then premiums going to the more scarce and desirable variations.
