While I finally opened my Dad's old tackle box, he has been gone for eight years I found some very old lures, and plugs. I also found what looks to be a bumper/shock absorber of some kind. It almost looks home made. Dad was a metal worked, tin basher in the Air Force and then again in Civilian life working for ConAir Aviation making Fire Fighting Planes. It looks like a Brass cotter pin inside a copper tube. The cotter pin is spring loaded. Has anyone ever seen something like this before? I can pull the one end out about one inch.
