The vises of my dad - while visiting this week - went out to see what we have had in our vise life for many many years. Do not recall anything bigger ever - and Dad has repaired everything from kid wagons to farm equipment on these small vises in addition to making (among other things) a spiral staircase to the second floor.
All well used, appear to have been generally abused as well. Took a lickin' and still tickin' for the most part.
If anyone or the spreadsheet needs more info - let me know.
Columbia 43 - had since I can remember - Dad says it came from my Mothers Father's workbench at some point in the 1960's.
Littlestown 25 - from about 25 years ago - probably broken when he got it at an auction.
CB&F Co No. 40 - likely bought in last ten years for his work in the equipment shed and never installed likely because it was more broken than he thought.
