Have an old Marco Enterprises TK. The more I see approved TK's, the more problems I see with my bucket, so I conclude it's for the display shelf only as my first non-Don Post TK bucket--almost 30 years old. I am thinking about making a sandtrooper out of the rest of the armor, some having yellowed in the years it has been in my garage. Definitely need a new helmet, but don't want to pay a mint, since I'll have to weather it anyway. Are the "Star Wars--The Black Series" helmets approvable?
