This listing is for a vintage oar lock.  It is brass or bronze.  5 inches in total length.  Inside the loop hole is 2 inches across.  I cannot find a year or maker on it.  Used and still in good shape.  Use the 'super size' feature on the pictures to get a better look.

I offer $6.99 Ground Advantage shipping in the United States and calculated shipping for international buyers.  Thank you once again.
