Ive seen a couple 30 20s Sterlingworths pop up on auction site in the last year. Each brought very good money, more so when you look at their well worn condition. Who knows what a real gem would bring and I doubt we will find out anytime soon. I suspect each pristine 30 & 32 20 is spoken for many time long before it comes up for sale. Those will never hit the auction sites. A few are owned by members on this board but none are for sale l am sure.
