Can someone help me ID this Barnes dry sump oil pump?

A friend gave this to me off of one of his race cars in case I needed it for the 68 Camaro I'm building. It was working fine when he took it off, but I am using a wet-sump system in the car and can't use it.

I know it is a Barnes unit, but I have never touched a dry sump system before and I have no idea if it is 3-stage, 4-stage, hypermumu-stage, whatever.

Can someone clue me in on some details and what it might be worth? I listed it for $400 seeing that new 3-stages for for about $1000. Is that a fair price?

Got it, a Sprint car guy clued me in. This is a 5-stage unit and he said it was worth about $600-$800. 8)

It is actually a 6 stage pump.
