I have mastered somewhere in the neighborhood of 100 model car and truck bodies that have been cast and offered for sale to the public, and probably another hundred seats, interiors, frames, dashes, hoods....etc. In most cases the master was placed in the hands of a caster, and I was compensated, either in resin copies, or cash. Once those masters were out of my hands, they were no longer my property....Someone else casts a copy, it's really not something I worry about. Now, I'm casting and marketing my own series of wheels - someone buys a set and casts them, I really have no recourse...Do I like it?....no. Am I going to lose sleep over it ? Hardly, that's just life. As an aside, I have personally heard some of the biggest names in the casting business scream bloody murder at someone possibly casting versions of their product, while quietly casting someone elses 'stuff' themselves.....I sorry it happens, get over it, go on with your life....Steve Zimmerman
