I'm loathe to give out Bob's email, but Mike Reagan's email is readily available through this website. Start with Mike would be my suggestion. He may have the answer and if he doesn't, he can pass along your inquiry to Bob.
Bob Krivacic is on the OGR Forum. You could search for his account. Landsteiner's suggestion is the best for a quick contact, though...contact Bob through Mike R. if you can't locate Bob on the Forum.
I've known Bob for nearly 25 years and he's almost always willing to help.
I emailed Mike today. I’ll wait for his reply. Thanks for the help gentlemen!
