Probably, if they are a suitable combination for some thread....
But, maybe he figures if that is your decision-maker, you aren't serious. If it is a change-gear lathe, and only had 2 gears, you need lots more, and can deal with whichever are present.
Might be nice to know if you were looking at getting the other ones...but they wouldn't help if you are out-bid.
Me? I wouldn't worry. Just move on. An ebay machine might be any junky thing at all, unless you are able to go and inspect. Might almost be worse than no lathe.
BTW, I counted at least 5 gears present on that machine.
And it appears to be assembled out of different parts, FWTW. The carriage assembly is painted different from the rest, that may have been replaced.... could be good or bad.
