FWIW, I saw an engraved 16 listed in the $1300-1500 range that sold Feb. 2006. Don't know what the actual selling price was, but the engraving was identical to Hallowell's 12.
I have to admit to abusing the 16 I have with loads and weather for the last 5 years... it keeps on ticking, but I'm always on the lookout for a parts gun in case it ever fails.
