Value by condition. Over 75% steel and good walnut... Minimum $500 IF serial number is <250000
If it was made after 12/31/68, a serial number should be clearly marked on the receiver. If made earlier, it may not have one or it may be hidden almost anywhere.
Depending on condition, between $400-$450.
