Unbranded (2x) 4"x1"x2" Magnetic Transfer Blocks (1x) V-Block 2"x2.35"x1.88". No markings on them whatsoever, I'm assuming these are shop-made but the rectangular blocks DO look a lot like Brown & Sharpe (which do come in that size). The V-Block is probably Shars, based on the construction.

Please see all pictures to inspect the condition for yourself.
