Yes, Dave. You have a problem. But what a wonderful problem it is.
You usually can't determine exactly when a lens is made by the serial number, but one that low indicates that it is firmly in the earliest runs. I'm not absolutely sure, but I'm thinking that the lowest one started at 106000. The Blacknosed version pretty much starts at 120000. There are outliers in the sampling data that was gathered a few years ago, but we came across no samples at that time below 106000.
