Gunbroker.com has Timber Wolfs in .357 at least once a month.
With 9000 imported, they float around. (It's where I got mine.)
Typical price is about the $450 - $475 range for decent Timber Wolfs.
NIBs go for closer to $600 - $800.
As for the Timber Wolfs in 44 Mag (only 1000 imported), one sold last week on Gunbroker.com for $1250 (or more.) $1250 was the second bid on the rifle.
It's the ONLY 44 Mag Timber Wolf that I have seen for sale. Period.
Hope that helps.
