Yesterday, despite a lingering head cold, I visited a newly opened shop that the owner calls a junk shop. I picked up a few useable items and a couple of curios. I found these pliers amongst several dozen sets. The replaceable jaws caught my eye. A bit unusual. $3 CAD

This 4" LS Starrett scriber and the parallel clamp will be useful. $5 CAD/pair

I found this J Whitworth thread chaser with 3/16 chasers installed. $8 CAD. There is obviously something missing that adjusts the two moveable chasers against the fixed chaser. Something, perhaps a parallel wedge affair was used. Can someone help or comment on the missing part(s)?



The adjuster would have fit into this slot.
