100-450 or so
100-400 USD
If this is a Winchester Model 70, and I'll bet it is since that model was a bolt action available in .338 Win Mag, that serial number puts it in 1949 according to the Blue Book.

Would greatly depend on condition.
First lets get the name right. Colman never made a model 338, Crosman did. So it's a Crosman model 338. You will need this information to get it fixed. Crosman offer a service to get older model air guns repaired. Go to the link posted below and open it. On the Crosman home page, click on "find a service center" at the bottom of the page. Then follow the instructions to locate a repair center.
