VINTAGE BARBWIRE FENCE STRETCHERS "AS IS" PARTS/REPAIR

Description

VINTAGE BARBWIRE FENCE STRETCHERS "AS IS" PARTS/REPAIR.
Picked these up at a estate auction.  Don't  know a lot about them.  Whether  they are complete or need other parts is unknown.  The 2 on the right have what looks like oak 1x1 1/2" board with a metal strap that wraps around it.  The hinged cast piece on the one in the middle is froze.  I will try to get it  release.
The piece on the left is surely missing something.the metal end looks to be able to accept another piece.
The long piece is 50" long.  All 3 with packing material will weigh 13 lbs.+.
Right now USPS has a charge on any parcels over 22" long.  I have no control  on postage.  I put in length and weight and Ebay calculates from there.
Please see photos and contact me on questions.
