Thanks for the response ginni. I have added a picture of the bottom of one of the figures to my website
http://home.mindspring.com/~nowello/ although it may not be much help.
Unfortunately, the bottoms have some kind of resin or coating which hides the actual bottom of the figure. I'm guessing it was to protect whatever surface the figures are placed on. I tried to remove the coating but couldn't. It is rock hard. If there is a way that you know of to get this stuff off, please let me know and I will try it.
Thanks much for your help. :lol:
