Miscellaneous "One of a Kind" and "Factory Seconds"

We have a limited selection of unique "one of a kind" specimens that are individually priced. These have been accumulated during previous test runs over the years. Some may need a bit of loving care, elbow grease, and some Novus polish to bring them back to their full beauty.

We also have a limited number of standard specimens that are less than perfect. Many have a small (1/2" or less) fracture in the area where the discharge exited the plastic. These defects can often be hidden by simply inserting the specimens into one of our custom lighted bases. Others may have heavier discharge areas near the main discharge "stem" or root that are slightly charred from the passage of high current. Although this makes these specimens somewhat less attractive when not illuminated, these specimens often are often some of the most interesting since they typically contain very unique patterns and combinations of chaotic and dense dendritic discharges. They become unique and very attractive specimens when edge illuminated by bright LED's, as the light is reflected and refracted off the chonchoidal fractures in the pattern. This can be seen in the "Heavy Weather" specimens (Style 16), where a combination of "snowflake" and chaotic discharges occurs. A rotatable 3D image of a lighted "Heavy Weather" specimen can be seen here (thanks to Theodore Gray - warning: large file size - will take some time to download completely)

More "Factory Second" specimens are available (sorry, no photos):

Depending on the nature of the defect, we have a large number of specimens that are priced at 30-50% of their more perfect counterparts. Some may have a small chip or fracture (usually at the site of the discharge), while others may only have an extra "ding" from an unsuccessful discharge attempt. For example, "factory second" Style 8 figures are priced at $44 -$55 versus the regular price of $110. Not all styles have "seconds". Currently available styles with one or more "factory seconds" include styles 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 15, 16, 17, 19A, 22, 23, 24, 28, 29, 31, 43, and 45. Please describe which "one of a kind" specimen or "factory second" style(s) you want and I'll try to provide one, but remember that it's first come first served  - when these are gone they're gone. I will try to put some more photos here soon.
