Correct. I'm was assuming it either comes with one or you have one lying around.
I find it very effective to bargain based on actual expenses you will have in getting it running. If there's no dustcover you can tell them how much that will cost you. If no headshell or cartridge you can tell them how much that will be. Someone might grok at a lowball offer initially but when you tell them your realistic total investment, they're more willing to negotiate.
For what it's worth I got a 1700MK2 for $70 and my total investment is closer to $300, perhaps more considering a few bad idea purchases
