Sometimes I am confused by what people call a Style 2, which is a Wild Rose engraved tricone and what exactly a Style 2 1/2 tricone is.  This is my attempt to clear it up.  First is my prized National a Style 2 1/2.  Now my understanding is that when there is extra rose and leaves on the coverplate that this is a Style 2 1/2, which actually was the first type of Style 2 ever released by National.  Mine is SN 0474.  Kellerman's book says there are only 2 such style 2 1/2 roundnecks, but I have seen several more in existence.
 The actual coverplate strap is devoid of any engraving, as you can see in these first 2 pictures.  The sides and back are standard Style 2 engraving.  Now, what we have come to call Style 2, actually came into existence after the 2 1/2 and only had a single small rose on the coverstrap of the coverplate and no extra fronds on the coverplate.  This one is one that I previsously owned and was SN 0541.  Again the back of thsese is the same as all other style 2s.  Finally, NRP has incorporated both Style 2 and 2 1/2 into their offering of the Style 2 and they have a rose on the cover strap as well as extra roses and leaves on the whole coverplate, as well as the tailpiece.  Maybe theirs should be called a Style 2 3/4!  I feel NRP's version is quite nice and is an excellent value for the dollar for an elaborately engraved tricone.
