How much should I ask for a Quincy 230-32 air compressor in good condition?

I acquired an old Quincy 230-32 air compressor pump and motor from a friend. It had been overhauled a few years before, and still worked well. It’s too big for me to use, so I’m planning to sell it. Looking online, I saw a refurbished pump for over $2,000 on eBay, with no motor or pulley. So I have no idea what I should start my asking price at.

I should add, I have no intention of asking anything close to $2,000. I just have no idea what a starting cost would be on an old compressor like that, as they are very good compressors, but, still, old

It's 60 years old! 
Are you giving a warranty??
