Following Mr. Pocha lead here are a few 143's that I have always enjoyed. The first is what I would call rare is a low wire groove no emb. rounded base 143 the colour on it is what I would call very vibrant blue not sure what name to put on these I have only ever had 2 in this colour this is the better of the 2 the other found a new home 10 years or so ago in the low three figure range.
Second are 2 no embossing whittle molds. left one is a weird colour is a sage green just above wire groove down the top portion I would call smokey grey the right one is a sagey green colour.
