I don't think that is the case Jack. While the #1 was and still is the most popular model, I do not believe there was that much of a surplus of HKL sheaths, and that there may have only been a number enough to ship some knives maybe into 63. Of course there is the possible straggler but most often in a different model than a model 1. The reason I know this is you will almost never see a model one with the shallow choil and wider ricasso in anything but a baby dot or possibly a Johnson BB.

You have to remember, Johnson was up to full production in 5-6 months and HKL was already done. They were done in 62. So, if there was 50 HKL #1 sheaths in stock, they were gone in a matter of months. Johnson was already making BB sheaths, so you were apt to get that during the time frame going into 63.
