If anyone is interested, I have two unused Saunders Machine Works (SMW) MR-1 Modular Vise Pallet - 20" x 6" x 1" 6061 Aluminum Vise Subplates. (1/2” Modular vise system not included but available from SMW)
They are currently sold out of the subplates online.
I upgraded to the full size plate. Love the system.
Message me directly if interested.
