Drill Jig Name

We need to replace a drill jig fixture but are having trouble finding a replacement apparently because we don't know it's name. The one we have has an oval shaped foot print. To open the fixture a handle is raised. The handle is attached to a shaft sticking out of the base. When the handle is raised it rotates the shaft which in turn raises two posts, one on each side of the fixture. These posts raise a jig mounting plate. A new part to be drilled is placed on a pedastel under the jig bolted to the bottom of the jig mounting plate and the handle is lowered. This pulls the drill jig down against the part clamping the part between the drill jig and the pedeatal. Has anoyone heard of this type of fixture? What keyword would be a good search word for this? All ideas, suggestions, and comments will be greatly appreciated. Thanks, K.
