Unless you can find someone who NEEDS a gang drill, I would say that is darn-near-worthless as-is. That has a HUGE footprint for a drill press without any real 'advantage' to a hobbyist. So the only folks you could sell that to are someone in production who NEEDS a gang drill (at which point, I suspect they would have already bought 'new' or from a dealer), a collector (if one exists), someone who wants to rip it apart for parts for another project (and thus won't pay much), or someone who has a LARGE shop space that they don't mind wasting that much room on a drillpress (basically a unicorn!).
I really think this is going to be one of those things that sits in the niche of 'Super expensive new, dirt cheap used' kinda things.
