Record Buck is a large operation with a lot of different citrus varieties so they may well have more than one type of limequat. I can say that when I called them year before last to ask specifically what variety of limequat I had just bought from them they said it was a Lakeland. I have a Eustis now as well (not from them) and it's fruit are somewhat rounder with no noticeable neck to them.

I'm hoping to pick up a Tavares at the expo in a couple of weeks. That one at least is pretty easy to distinguish from the rest.
