Help ID'ing a Vise

[AJHbike]

Just picked up a pair of vises and am wondering if this is a Rock Island. The only marks say 3 1/2. Thank you.

No ideas as to origin?

This looks like a Wilson oval slide vise to me. This is a late 1800s catalog image. Yours appears newer.

Thank you...It does look like a Wilson!
