That is special! Obviously your father was something of a craftsman.
I'm very proud of my Father. He was the inspiration for me from a very young age. He built Billiard Tables, Bumper Pool tables (I have his last restoration), Mini Pool tables - even his own Video Cabinets. He migrated from Italy in 1955 with the equivalent of 20 pounds in his pocket after enduring WWII.
He taught me how to troubleshoot EMs and 1950's Bingos when I was 14 years of age. I plan on teaching my son the same thing.
