With the help of Wizard of Flight, I built a new keyhole detail based on his amazing drawing and scaled overlay he made up for me. Thanks a bunch Alan Your talent continues to help us all. The best part of the new piece was that I was able to cleanly incorparate the MQ-1 right into the casting, meaning no more cutting and filing away the holes. It takes a fraction of the time to plug in the new detail than to do all the other work.
Thanks again Alan! keep up the good work.
