I loved to see the "Want to buy" for this thread title.
The great thing about Swedish Mausers is they are a military arm. The miltaria collectors loathe sporters and they punish the values of any modifications whatsoever.
As a result, a broad suppression of value has occurred:
Group 1: The shadetree gunsmith that bastardized a Swede Mauser with a hacksaw, then bent the bolt down, and stripped the military sights. (I get it, near worthless, ruined)
Group 2: Mid-Century US custom sporters built to Griffin & Howe / Sedgley / Niedner / Hoffman / other best builder standards of care. These guns might cost $10,000 to build today. They sell crazy cheap, a $10,000 quality example might be less than $3000. A very good quality utility grade custom rifle might indeed be found for $700-$1100, especially if a militaria collector decides to price it at a gun shop. "Just another ruined military mauser, throw it on the discount rack".
Look long and look hard, there are amazing custom Swedes out there, do not settle for anything less than exquisite.
