They seem to be fully vetting everything going to non-SOT's. If it goes to an SOT they seem to pass it through even if it's incorrect information. Of the last 8 that needed corrections all had been recently transferred to the SOT without any corrections, then when they came to me, the corrections suddenly became an issue. It's likely they figure if the gun becomes an issue it's always available for inspection at an SOT's location on demand. Once it goes to an individual, it may be decades before it can be seen/inspected again.
IIRC Doug did not release the sterling tubes until the early 2000's in two or so separate batch offerings and that seems to be when Rick bought them and got into it? Recon bought significantly more (at least double from memory), had the Andrewski's build them and sold out years ago. Form 4's to an individual from another individual take about the same time as from a dealer. Prioritization is given to SOT's regardless of the form.
