There were a few made over the years in many variations, such as I ivory butt, cap, Ivy, joints and ferrules, leather wrap, some with spear head points with mammoth Ivory dots in the points, floating points between the main points with Mammoth Ivory dots. I also own one that has Ebony pointed shafts with ivory Ferrules. I will tell you this I will buy them all day long for 500-900$
There is still a very large following in eroupe
A lot of information can be found on my Huebler page on Facebook
