I've known quite a few Ruger collectors, but none of the primary players. The Ruger Collectors Association was formed in 1975.
In 2010, someone bought a former Ruger employee's collection. All serial numbers ended in 0038. The ad explains the mixup that led to Bill Ruger giving the man the claim on number 38 - because Mr. Ruger claimed all the numbers from 1 to 40 for himself.
The selling price was $29,500 plus fees, etc. The buyer's premium alone was almost $6k.
