Uh, they seem to be the same gun. Look at the serial number in each example. Also,I can't find that particular range of numbers anywhere in the listings. I looked in Cobra, Agent, Aircrewman, DS and PPS.
gerhard1, I have my own database of S/N's. It is not complete by any means, nor does it cover all models for all years.
We all know that there is no published S/N data past the mid 80's. So, as my collection grew to include multiple examples of the same model, I have been able to peice together broad date ranges based on guns in my collection.
This is also how I am able to provide some folks with DOM for modern guns, like the forum member who had a modern Anaconda and wanted to date it.
Still the best way to obtain a DOM for any Colt is to call the manufacturer directly.
