Re: the four-in-hand tie. As mentioned earlier, that is the regular tie, to distinguish it from the bow tie. (there are others but one rarely sees them). for the four-in-hand there are three (at least) ways of tying it, each gives a slightly different appearance to the knot. With the four-in-hand the knot is almost tubular, only slightly tapered. The half-windsor is more triangular in shape, and the full windsor is very wide at the top and almost an equalatteral triangle. Probably the half windsor is the most common, but I wouldn't put any money on it.
