Very very sad to read this.He was a good friend.
I first met Frank when you could see full eBay ID names back some 20 years ago and contact each other.
He contacted me after I outbid him in an auction,and asked if I would sell that to him.I told him no,but would guide him to another if I see another one.Years later I did & notified him.He was very grateful and we struck up a small friendship through the internet.
Both of us sharing our collection & finds with each other for years after that.
Rest In Peace Frank.
