Small Bronze Block with Shackle and Becket - Marine Pulley

Description

This is a sweet little block that can take a rather large rope for it's size.  In the picture is 3/8" hemp but could could squeak a size larger if needed.  Sheave size is roughly 1 1/4' and total length from shackle to becket is 4 inches.  The sheave moves well with no wear and the shackle it tight.  I don't think this has ever been used appears to have been stored in a locker its whole life.  The background grid is 1 inch squares for reference
I've got a bunch of surplus equipment coming from our refit of an old pilot cutter and other projects.  Feel free to ask questions if anything is unclear or if you need exact dimensions.  I'll sometimes be a bit slow as we don't have good internet at the yard so be patient.
