Savage model 6

Looking to sell my Savage model 6. Made in the 1930s This is the predisesor to the click clack rifle's everyone is familiar with. The difference is this rifle dose not lock open with each shot. Instead functioning as a normal semi auto. Last photo shows the mechanical difference of the A6 vs the model 6 

Looking to get $500 + shipping for this rifle, but open to to trade offers for anything antique or interesting.
