PS&W 1 1/2

Can anyone please tell me about how much this old PS & W 1 1/2 is worth? My 10 y/o son was given a few traps by an older gentleman and this was in the box. Thanks!

With the broke spring and chain it is a wall hanger or parts trap. $5 or $10

Thanks, kinda what I thought, but didn't want to ruin something important.

The pan is more readable than many. Great wall hanger 1870 - 1920, I think.
