I've got a medium size vise on my bench at home that has no markings but probably 80 years old and still going strong. Serves my purpose well and gets used alot, but not for heavy applications. I do not fab metal or weld, so more or less more clamping. My dad has my grandfathers old anvil that is nailed down to an old hickory stump, the anvil itself probably weights 200 lbs., and I'm just too busy to go pick it up. Anvil is probably from around 1945 era - maybe try blacksmithing in my retirement.
So it's not a need, but do have interest in tools and some of the older vises I have seen on this forum. Space is an issue, as I am swoll up in my home shop, but primarily work with wood anyhow.
Some of my background:
Building residential housing
Army Engineer
Dent Doctor
Farm maintenance
Outboard motor repair
Shadetree auto
Motorcycle repair and maintenance
Have dabbled in most of the trades as well.
However, mostly relegate myself to "side" jobs that mostly include deck construction, fences, landscaping.
Currently my "real job" is in education medicine and have extensive history in applied psych, but now admin in my later years.
