Date/Columbian Vise ID? Model 72

[kjspgd]

I recently acquired this but am having trouble dating/finding ads related to this.

Model 72
3.25 (3 1/4") jaws; 4.5" travel open
Center mount swivel base - but it's handled by a nut from below - no hole through the casting to adjust swivel.
Has round/ball-style handle keep - vs the cylinder style I'm used to see on other Columbians
Swivel base has a number - 151

Any ideas on date or what I've got here? I'm trouble finding info on the model.

Thanks!

Most guys on here believe those types of bases on US vises are WWI era and earlier.

Nothing in ITCL. That type needs a center post to anchor it to the bench, and loosen it to pivot.

Think I found something in this (listed as) 1907 ad on ebay. It's the only reference I've found to the columbian 72 that was not a later model gyro vise.

I've come across many vises. Never seen that model before. Definitely looks early.
