For your consideration, here is a Pair of Old Machinist 4 Inch Parallel Clamps, no. 4486, made in the USA.  Both have some wear and some tarnish on them.  They work great and tighten up fine.  They will be mailed in a box for protection.  Please contact me with your zip code, for a shipping quote.  The shipping may be less than what is stated in the listing.  Items pictured are the actual items up for sale and come from a non-smoking household.  (418.204e-PriS1.8bx2)
