Or both of themLooks like someone's been in it, replaced one of the pins with a bolt.
I wouldn't count on that level of diligence.Or both of them
hmmm I'm not sure if it ever had lockdown pins? Couldn't this simply be a fixed base model? I see quite a few that look like this--with the square shoulder on the mounting holes? I wonder if this could be considered a 500 model? Even though its not stamped as such?Looks like someone's been in it, replaced one of the pins with a bolt.
If its missing a swivel base then that has happened to a lot of these. I've seen a dozen online that have the same square shoulder holes and no swivel. Mostly they are listed as fixed base models. Maybe that's the case here. I'll check the catalogs.Looks more like a "missing the swivel base" to me.
I'm referring to the bolts near the rear of the vise - those were originally pins. You'll probably want to replace those with set screws.hmmm I'm not sure if it ever had lockdown pins?

ahhhh those pins at the rear. I understand now. Thanks !Yes
The factory used quarter inch steel pins to fasten the long tubular nut in place inside the vise body.
It is my understanding that those vises were sold with and without the swivel base. With a base, the model number is 500S. Without the base, the model number is 500N
But that doesn’t matter. If you think you need a swivel base, be on the lookout for a used one or contact autopts on eBay. Of course you can just put some bolts through those 2 holes and fasten it to your workbench and get busy. That’s a fantastic vise. I have one (no swivel base) that I used to use as my daily driver before I replaced it with a Wilton C1 combination vise.
