please help identify this wilton vise

[markitsnappy]

I picked this up today. it's marked wilton des plaines. I believe it is made in usa. its marked 111146. its not a bullet but is still a sealed unit. anyone know what model this is? seems like a pretty nice vise. also picked up this dayton 1/2 hp buffer and a dayton hot air blower.

Looks like a Wilton 74X type vise. Replace X by jaw width. Here is an example:
